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.
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.
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.)
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.
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?
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.
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.
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?
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.
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.
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.
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.
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.
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.

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.

You're saying this as if it is a bad thing? I absolutely welcome this decision by the authors!

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

So not open source.
Are you miffed by the restriction on you selling derivative open printers?
- By rolling the paper, will it really stay flat after printing? - How easy / cheap will sourcing ink be?
