Why would they bother? They make all their money on the ink cartridges. If this drives more cartridge sales it’s a win/win for them. They generally don’t make much, if anything, on consumer ink jet printers themselves

It’s negligible revenue and carries some risk. Say the printer works well, and these enthusiasts drive a couple of thousand more cartridge sales. And that encourages someone to develop an alternative cartridge, which is mechanically and electrically compatible with HP’s. It just seems easier to fire off a cease and desist than to take a risk of other people messing around with your ecosystem.

This already happens for basically every commercially-available ink cartridge.

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.

I do wonder if they print end of page lines for you to cut afterward (sorry couldn't read the whole webpage, maybe they explained it)

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 pr…

Canon is still in the market, they just supply parts and license IP to the printer manufacturers like HP. They make some high value stuff to sell to the OEMs but I don’t think they can make a whole print head anymore.

The license doesn't apply to the things you print with it. Are you miffed by the restriction on you selling derivative open printers?

If nobody can sell me the printer or replacement parts for it after the initial vendor inevitably goes out of business, that's a problem.

They actually can sell you replacement parts, they just can't do it as a commercial endeavor. You have a point though.

If it is not an open source license, you should not call it open source. Imagine someone saying the same thing about MongoDB's license, for example.

Is there a Linux server run on fully open source hardware (what would that mean btw?)? Should we stop using "open source" because almost all computers are not fully open source?

Quite a lot of open source hardware is licensed under the BY-SA Creative Commons license which is an actual open source license. E.g. the Arduinos and things like the Milkymist One which can actually run linux.

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.

Ugh yes agree, that Prusa one was a massive misstep.

I don't get why this isn't an ink tank printer. Yes, those HP cartridges are technically refillable, but the printheads tend to clog up after a few refills, and then you are stuck paying retail for another cartridge.

It would be a lot more aspirational to figure out how to build a tank-based printer (although maybe its not possible to compete with the incumbents on price in this space)

I suspect the hard bit is the print head. So they’re just buying that in.

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 woul…

I had thought about a post-apocalyptic prepper printer once, my conclusion was that you can just have a fax machine and a laptop. They're considered thoroughly obsolete, and almost free to take in used markets as well.

Yeah, Building a thermoprinter is probably doable, and making thermopaper seems plausible as well
