> I must apologise that I haven’t so far open-sourced any part of this that I don’t have to. Mainly that’s because I think this would be an awesomely sticky web property for a printer consumables firm to integrate with their sales site. And I’d much prefer it if they paid me to white-label it for them, rather than just forking a repo and getting it all for free.
They might be interested if they cared at all about the ease of use of their printers
They are referring to aftermarket ink cartridge companies, not the printer OEM.
These printer makers have the source code and the ability to write firmware. If they wanted to support WebUSB, they could and would.
