Inkjet printing requires orders of magnitude more engineering expertise, materials science, industry experience and financial resources than most people imagine. That is the reason, open inkjet printers don't exist despite having been consumer products with the same drawbacks for more than forty years.
That is why this is a pre-crowdfund landing page without a demonstrating a working prototype. I would like to be wrong, but I expect you to be waiting a long time.
An inkjet printer is not a collection of off the shelf parts. It is a machine that operates at the edge of chemistry, fluid dynamics, and electro-mechanical design...you have to place tiny tiny drops of liquid ink on commodity wood pulp with precision under arbitrary environmental conditions, get that ink to dry on the wood pulp, but not in tank or nozzel, while producing acceptable color, durability, and ease of use.
Also lawyers...there are patents.
I noticed that previous post is from a couple of months ago, and it looks like about a week ago they posted a project update and they claim for their current prototype: "We are successfully printing in both black and full color." https://www.crowdsupply.com/open-tools/open-printer/updates/...
Of course I have no way of verifying either way. Still I do think the project looks quite interesting, I'm in the market for a printer and this is certainly the most interesting one I've seen in a while.
On the technology side, I'm somewhat hopeful because it looks like they're using off-the-shelf HP ink cartridges for this. HP cartridges embed the printhead into the cartridge itself, and that printhead is arguably the most complicated part of the entire device. Outsource the printhead, and you're just designing a plotter with a PCL interface.
I agree that the bigger challenge is going to be patents.
It also wouldn't surprise me to see HP add DRM to cartridges to authenticate the printer itself if this catches on. (Possibly requiring a printer driver/firmware update.)
Maybe they should have purchased a design from Canon or someone that isn't really in this market anymore. It seems like not only are they locked into a specific older technology generation (which could be ok idk) but they also risk HP just discontinuing that cartridge. It seems like the printers for this cartridge were released around late 2017 so they could deprecate earlier than they normally do. Seems like they provide 10-20 years typically. At the same time , maybe this is just meant for a small user base of nerds and maybe HP wont care.
> I agree that the bigger challenge is going to be patents.
Surely most/all of the patents around the actual inkjet printing function have expired though, right? I had inkjet printers in the mid 00s and if anything I feel like your average inkjet is worse these days.
I don’t see why HP would want to do that. They have huge margins on ink, right? I’m sure the increase in cartridge sales would offset lost subscription revenue from useless cloud services, if only because the people who are gonna use an open source printer would never pay for that anyway.
Yea, but then the print head clogs up after the second time you refill it and you buy another expensive print head + ink from HP.
Frankly, I think 99% of the reason they started integrating the print head with the cartridge was to avoid all the problems you so frequently see on printers that don’t use disposable heads.
The fact the campaign is run on crowdsupply makes me a lot more hopeful it'll get to market vs a site like kickstarter. Crowdsupply requires a working prototype before launching and they provide all the expertise to actually get projects to market, off the top of my head I don't believe any crowdsupply project has failed to deliver.
I have enormous respect for dot matrix printers. They're easy to repair and service, the tech is relatively simple, it's cheap, it's parts are cheap, its supplies are cheap. It's way more sustainable than any other printer: both the printer itself in its manufacturing and the ribbons themselves. The waste they produce is also much less polluting than any other printer.
They also kind of suck. I'm not one for "the latest and greatest", but their output quality is atrocious compared to modern printers, they're loud AF, and I'm guessing it may have existed but I never saw a dot matrix that didn't have the perforated edge for feeding.
Dot Matrix are still used in outdoor / high humidity environments in USA.
A lot of car shops with regular 100% humidity conditions will swear by dot matrix + tractor for feeding paper + printing. Plus, the carbon copy forms are guaranteed to be exact carbon copies which also leads to legal guarantees about copies of paper being provably exactly the same in the court of law.
Pen plotters could accept sheets of A4 and very precisely position them since at least the 80s. I'm surprised that dot-matrix printers didn't adopt similar technologies sooner, though it could be because by the mid-80s dot-matrix printers were the budget option, fanfold paper with the tractor strips was still abundant, and it was much easier to just stick with the cheaply manufacturable technologies rather than take the risk of innovation with a product that wouldn't sell upmarket anyway.
99% of this is the printhead and the ink formulation. Assuming you use generic off the shelf solutions for those two components you’re set. All the printer companies do their lock in at the firmware and software layer.
Yeah, I found that original comment to be a bit nonsensical. It would be like arguing you can't build your own PC because the lithography tech needed to make modern ICs is really complicated. I wasn't planning a laying out my own chip, and these guys aren't planning on building their own printhead from scratch.
yes, I was about to build another gaming PC, and then I remembered the ASML machine costs 20 bajillion. Will wait for the ASML machine to come down in price, to around couple of grand.
Compatible cartridges
HP 63 and HP 63 XL (US)
HP 302 and HP 302 XL (Europe)
HP 803 and HP 803 XL (Asia)
So they just use HP inkjet technology. That makes it less open-source, but even "open source" parts are going to be under non-commercial license (CC BY-NC-SA) anyway.
None, in the months (sometimes years) it spends switched off (off, not standby) between print jobs. It's a quarter of a century old and I can still get replacement cartridges when I need them.
Extremely little? High quality inkjets may make sense for corporate or industrial uses, but the majority of home/consumer use cases probably print very infrequently these days. In that scenario inkjet is pretty bad because the ink dries out between uses - there is a reason it's such a common trope that inkjets never work right when you need them.
I switched to laser because I only print like maybe once a month on average (but when I need it, I need it). I'm not the slightest bit worried about the delta energy usage between my laser printer or the inkjet, and I'm sure the inkjet came out worse given the number of cartridges I had to throw away or paper I wasted printing diagnostics.
Which is why its more surprising this was first announced last year and there's no Proof of Concept demo yet?
But really, I've given up on ink jet printers, and have gone the cheap B&W laser route for anything I need to print at home (In the past year, 2 times, a backup ticket and some paperwork that needed a real signature sent back).
But when I had them, the thing that went bad 99.999% of the time was the cartridges or a clogged nozzle on the head. So the advantage here, on the repairability side not DRM, is the rails and motors?
Also that cutter is going to be a pain, having worked on Lightjet printers, that cutter was nearly all field service issues until the FEs started leaving the "laser" key so lab managers could reset the blade themselves.
An open source all-in-one-printer would be a great device to have. For eg I would love to have the scanner include a camera. So I can get “instant scans” most of the time, and a higher res scan when needed. Maybe the camera could also notice when the person making copies or scans forgot their original and ping them?
You'd probably need some basic custom lens (not crazy $$) that would distort the heck out of the image, but you could correct the shape in software. Given that GP wanted this to be the "low quality / high speed" secondary scanning option, the inevitable loss of quality would be acceptable.
Seeing chromatic aberration on a document scan would be strange, but this is basically how many document scans are created today (using phone camera + software correction). It's just the lens effects from this cheap lens would be a lot worse than what Apple/Samsung/Google can do with their super expensive to design custom lens stacks.
Try to find an typical consumer inkjet printer on AliExpress, you won't find any, or if you do, it will be someone reselling the usual brands like HP or Canon. You will find label printers, industrial printers, 3D printers, thermal printers, and all sorts of weird stuff, but none of them able to put ink on a stack of A4 paper.
If the Chinese, who are known for being able to make knockoffs of everything are not able to make inkjet printers, this should tell you how hard it is.
It addition to the print head, reliable paper transport is also really hard. That problem is often sidestepped by using a paper roll or by printing one sheet at a time, as it is the case for the Openprinter.
A more likely explanation has to do with the economics of ink jet printers. The ink sales are so profitable that HP and other manufacturers subsidize their printers. This leads to prices at or near cost.
Since Ali express vendors can't count on follow on ink sales, they can't compete on price. And competing on price is Ali express's reason for existence.
So, ink jet printer are harder to find on Ali express. At least, low end consumer focused ink jet printers.
Laser printers, which aren't subsidized are common
Several Chinese companies have their own domestic laser printers, claiming of in-house components and development (Cumtenn, ZoneWin), and one company does inkjet printers in addition to lasers (Deli Printer).
ZoneWin, a laser printer company, made a clone of both HP LaserJet 1020 and LaserJet M1005, which reuse most of the original/compatible parts (Q2612A cartridge). They claim it's 100% domestic parts only.
I think the top-ranking comment about complexity is off base: they're not inventing inkjet printing from scratch. It's basically a bunch of existing modules in a new package, presumably with the promise that you will not need to buy subscriptions or DRMed ink cartridges.
Is robustness and reparability a compelling pitch? If I'm counting right, I owned eight different printers in my life. Dot matrix, dye sublimation, inkjet, laser. I don't think a single one ever required any serious repairs beyond replacing consumables, clearing paper jams, and pulling out lint. I upgraded as the technology improved. My first laser printer needed about 4x as much desk space as the current one.
> I don't think a single one ever required any serious repairs beyond replacing consumables
I think your experience has been an outlier. I've had several printers from different brands also, and have had some that last a long time, and still print with decent quality even with off-brand ink/toner. However, quite a lot have also failed due to bad capacitors, bad power modules, or the printer or it's firmware just refused to work/print for whatever reason and the manufacturer response was: "buy a new one." There's definitely planned obsolescence built into these machines, and that's why people dislike them, aside from the fact they can be a pain to configure. That's in addition to the ink DRM and other shitty cartel like bs from printer manufacturers.
I would highly recommend getting a laser, especially if she isn't doing a huge amount of printing. You can leave them forever without printing and they'll just spin up and work in an instant. Both B+W and color ones are really decently priced these days.
I never had problems with Brother for laser and Canon for inkjet. The models I have are no longer being manufactured, so I can't recommend anything specific. I did my best to stay way from HP for inkjet, they always had bad rep.
> Is robustness and reparability a compelling pitch? If I'm counting right, I owned eight different printers in my life.
Like the other commenter mentioned, I think your experience is likely an outlier. But more to the point, the way printer companies make money (lose money on the printer, make it up on ink), the couple times my printer has broken, I just bought a brand new printer. I'm sure the printer probably could have been easily fixed but it wasn't even like that was a decent option.
This printer probably isn't for everyone but there are enough of us who are so fed up with "subscription fatigue" and locked down devices that having a tool that I fully own and could fix if necessary is appealing.
This is interesting, but it seems to be a crowdfunding campaign only. I wish them the best of luck (the cause is worthy for sure), but buyer beware at this point.
(I myself don't 2D print enough that an ink based printer makes sense for me. Ink tends to dry, so for me a laser printer that can sit for months at a time makes more sense. I use the scanner as well as my 3D printer far more often.)
I wonder how they will handle the nonsense around yellow tracking dots[1] etc. Hopefully that doesn't become a problem.
National security letters or old boys network or maybe just fat bribes to the right engineer. Could be a requirement for government procurement too, so not a law, just the requirement of a huge customer with deep pockets and negative price sensitivity.
Unlike now, where instead of saying your hypothesis you're just letting every reader come up with what they think is a crazy conspiracy theory and ascribe it to you?
As much as this is nice protect, and physical one so different things any, still you cannot give/sell some software/design/media and restrict who, where and how someone can use it (noncommercial, not in this country, not at that phase of moon) while calling it open source, public domain, or similar.
As long as softwsre isn't going to be proprietary, it is a good idea just shouldn't misguide about being open source.
I had an Epson Ecotank for a couple of years. The printer heads got clogged all the time. We bought a series of cleaning products to address it, they often solved the problem for only a few prints. We finally gave up and bought a Brother laser printer.
This project seems like it's trying to address a similar market to the Ecotank. What assurances can the project team provide that OpenPrinter will have better reliability?
I have an Ecotank and my parents have one too (data set size of 2 :). I've had it for 4-5 years now and it's superb for my simple use case (occasional low cost printing at home).
I did initially run into clogged heads too, until I scheduled a test print every month which uses all colors. That way no single color stays unused for too long, and it's been working like a charm ever since.
If the heads are already "degraded" there are two (or more?) cleaning programs available from within the official printer driver settings dialog. They did resolve my initial issues.
Epson could definitely do a better job of informing users though by slapping a big warning on the thing saying "you need to print something every X days to avoid issues".
I also had an Epson ink-tank printer (I don't think it was an Ecotank model name, but similar idea) for several years, battled print head clogs all the time. Found that Windex worked pretty well for dissolving the clogs. (The dad from My Big Fat Greek Wedding was right about something!) But what eventually got me to switch was that the maintenance cartridge — the big sponge under the printer that soaks up the ink pushed through the heads during a head-cleaning operation — was getting full, and it's not a user-serviceable component in Epson printers! They wanted me to ship it off to their service center, and pay who knows how much to swap out the maintenance cartridge. Nope, not gonna do that.
Ditched Epson for Canon. I've had my Canon ink-tank printer for a couple years now. Had ONE serious clog that required multiple flushes to clear the clog, but mostly it's been clog-free. But the best part is that I can just order a new maintenance cartridge from Canon for about $12 + shipping. So when it fills up (probably in another couple years) I can just swap it out myself and keep on printing.
Won't ever buy another Epson printer again. Canon has been great so far.
If you print occasionally then laser is the best option. It's just not usable for photo printing. You ideally want to be using the printer every week or two with inkjet.
It sounds like OpenPrinter will be using existing ink cartridges with the print heads built-in; I presume they will therefore have the same reliability.
Unless I'm missing something using this in a commercial application would be a license violation:
> Open Printer is distributed under the Creative Commons BY-NC-SA 4.0 license.
> This means that everyone is free to use, share, and modify the project, provided they credit the original author, share derivatives under the same license, and do not use it for commercial purposes.
It's also not opensource yet, there's a vague mention of "when its ready" it'll be released.
This is probably inevitable at this point and at least it's a legit licence and not the weird sad bespoke wobbly nonsense Prusa went with. They clearly need something like this for exactly the same reasons.
What about that license makes you think you can't use the device (i.e. print things) for commercial purposes?
The license applies to the thing, not the thing you print using the thing. Me writing software or prose on a computer running Linux using a GPL editor wouldn't change that the copyright of what I write belongs to me, the author.
You can't make a commercial competitor of this printer using their design, but using the printer for its intended purpose (printing) is obviously unrelated to that.
> You can't make a commercial competitor of this printer using their design
Which means it's not open source. Open source means you have the right to distribute work however you want, including commercially, provided you also provide the source under the same license terms as the original.
The second you slap a non-commercial limitation on there, it ceases to be open source.
I didn't plan to go into the printer manufacturing business, and there's nothing more open, AFAIK. HP won't let you fix it when they brick your printer for not using their more expensive than blood ink.
It may be using a CC license, but nothing that's marked NC is meaningfully part of the commons. Yes, some guy can make a part to fix his printer, but that guy can't sell those parts to other people.
The existence of a service manual doesn't mean you can get parts once the company disappears or loses interest.
I really love the idea of a paper roll rather than individual sheets. Being able to print out to the size you want rather than only in pre-set sizes is quite cool.
TL;DR: I'm surprised this isn't a laser printer, as those are actually quite a bit easier to design and manufacture, especially if you can use a cheap, older, commonly available, remanufacturable toner cartridge.
There are still quality laser printers on the market without extortion and surveillance built-in, unlike inkjets. The need for an open laser printer is less dire than for an open inkjet.
Every manufacturer volunteered to rob their own customers of anonymity. Even at the OS and application level (Adobe) people are being tagged with robust watermarks. In general, still no one cares. =3
And not a single solid-ink-onto-paper sublimation printer, that I'm aware. There are badge printers still using a dye-sub ribbon, but the Tektronix Phaser, later the Xerox Phaser, is completely gone.
I wonder why. Were the consumables too cheap and the printers too reliable to be commercially viable? Did color laser printers catch up in terms of print quality? Did it have some other fatal flaw?
Hot melt ink/solid ink has a laundry list of problems that complicate it.
- A single ink clog can destroy a printhead.
- partial clogs can result in ugly messes with ink smeared all over the pages and the assembly further smearing on later prints.
- the printer has to be calibrated to the specific formulation of solid ink to work properly. A bad ink batch or calibrating to the wrong formulation (or a drift in specs on the formulation) can cause clogs, print head failures, etc.
- solid ink printing massively complicates lamination if that's something you need to do (ex in an office).
Overall it's a far more unforgiving process. You can't really have aftermarket inks like you can with modern inks and even variations in the first party manufacturing process can have catastrophic effects on the print hardware.
I was hoping to see a printer that say a prepper could build from scratch. This design 100% depends on commercial print cartridges containing the actual print-head. Once that clogs, you need to get another one, good luck getting one once production has stopped.
Also, if you wanted to avoid yellow dots, not sure if this is built into the cartridge or the firmware of the rest of the printer.
Now, I understand that would be hard to pull off. Maybe one could build a deskjet500 equivalent one.
Laser printers are quite complex as well, you need too many non-easy to build from scratch parts.
Maybe a dot matrix printer is possible.
I know for sure you can retrofit older electric typewriters, and those are pretty repairable.
>Please don't complain about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage. They're too common to be interesting.
Been waiting for framework to make a regular 2D printer, of any kind, would buy at least two instantly. I will never, never, never buy a fing printer from hp/canon/epson/brother/etc with anti-consumer tech, I rather die.
close, but not quite. I suppose in the way that originally set him off, yes.
It looks like they're using the Creative Commons BY-NC-SA 4.0 license so restricting commercial use which I think would run afoul of the purists definition of Freedom?
It's a cool printer, and I'd much rather have something like this!
To be less facetious though, this seems like a nice project (*), but I print so much less these days than in the past. I printed a lot of color stuff when I was in school; but these days I just settle for black/halftoning from a laser printer, for when I actually need something printed, and color on screen only.
---
(*) - except perhaps for the NC restriction in the license.
It's such a good idea as a project and by the looks of things well executed. I also feel the style of the printer and the fact it can be a roll of paper will lead to interesting project ideas.
Does "open source" even mean something anymore, or should we give up and just accept it as common catch-all phrase for everything that suck less, without one definition?
Open source AI without a source. Open source software, oh but only up to 4000 users after two years of release for people on south hemisphere. Now open source hardware but your copies of design are for noncommercial use, only our copies are not restriced.
If they don't do this (noncommercial, patent), the lesson is that a succession of Chinese vendors will take it and perhaps even secure patents on top of their work. They want time to finish it their way.

They're noisier than ink printers, but non-industrial quality can be pretty reasonable for office-level noises.
Quality certainly isn't on par with laser printers, but for text (both Latin and CJK), it's perfectly clear.
A lot of car shops with regular 100% humidity conditions will swear by dot matrix + tractor for feeding paper + printing. Plus, the carbon copy forms are guaranteed to be exact carbon copies which also leads to legal guarantees about copies of paper being provably exactly the same in the court of law.
You're saying this as if it is a bad thing? I absolutely welcome this decision by the authors!
But how important?
Imagine someone saying the same thing about MongoDB's license, for example.
I switched to laser because I only print like maybe once a month on average (but when I need it, I need it). I'm not the slightest bit worried about the delta energy usage between my laser printer or the inkjet, and I'm sure the inkjet came out worse given the number of cartridges I had to throw away or paper I wasted printing diagnostics.

They've been around long enough that you can find them all over the place used for quite cheap and they likely only need a cleaning.

What's there to handle? They just don't include them and there's no statute that requires them to.
So not open source.

Also, if you wanted to avoid yellow dots, not sure if this is built into the cartridge or the firmware of the rest of the printer.
Now, I understand that would be hard to pull off. Maybe one could build a deskjet500 equivalent one.
Laser printers are quite complex as well, you need too many non-easy to build from scratch parts.
Maybe a dot matrix printer is possible.
I know for sure you can retrofit older electric typewriters, and those are pretty repairable.

It looks like they're using the Creative Commons BY-NC-SA 4.0 license so restricting commercial use which I think would run afoul of the purists definition of Freedom?
It's a cool printer, and I'd much rather have something like this!
To be less facetious though, this seems like a nice project (*), but I print so much less these days than in the past. I printed a lot of color stuff when I was in school; but these days I just settle for black/halftoning from a laser printer, for when I actually need something printed, and color on screen only.

Some previous discussion on the crowdfunding:
Inkjet printer with DRM-free ink will be launched via a crowdfunding campaign (2025)

Open source AI without a source. Open source software, oh but only up to 4000 users after two years of release for people on south hemisphere. Now open source hardware but your copies of design are for noncommercial use, only our copies are not restriced.
