This is a device, to which you connect your older USB printer, and use it from any PC or smartphone without installing drivers (AirPrint/Mopria), wirelessly. As easy as that!
* Supports all OS: Windows, macOS, Linux, iOS, Android. No drivers needed. Windows-on-ARM and Apple M1/2/3/4 also supported.
* Supports the majority of printers released before ≈2018
* Profit from sold devices is shared between CUPS, SANE, AirSane open-source printing and scanning projects
* Surplus and donations are accumulated to improve current open-source drivers and develop new ones
The printer driver is run inside the device. It comes with lots of open-source and official proprietary drivers. x86-only drivers are running under box86 emulation, with little visible performance impact, ensuring wide compatibility with many printers and MFPs.
All of this is bundled in a retail-like device, with simple web interface[1][2]. No tinkering and no DIY required, it's safe to plug off the power cord every time, and you can do factory reset.
The print server is secure by default: it conforms to most of the IoT Device Security Specification 1.0[3] best practices, has built-in firewall to ensure LAN-only operation, and does not include anti-consumer features.
All devices come with technical support, where I act as a middleman between all the involved projects and printer drivers. If there's a bug, I first try to debug the issue remotely, and if it's not possible, end up buying the same printer and debug it until the issue is resolved.
All the fixes made during the development are contributed back to the origin projects, and there were many bugs fixed: almost every package has additional patches compared to original Debian 12 disto state.

P.S. Brother printer lovers, the latest Brother L2800dw (2024) laser comes with the chipped cartridge, which you can't refill and reset forever anymore. The printer allows to continue printing with an "empty" cartridge with a special menu item, but it does so only to fixed amount of pages, and then stops. It doesn't allow to use cartridges without chips.
I had to do something similar to get an old Epson scanner to work. It astonished me that there are no drivers for it on the Epson website, no generic or legacy Windows drivers. And this was a serious hum-dinger of a scanner which is still much better than a brand new Epson because, shockingly, it's really hard to buy a decent scanner these days. They're ludicrously badly made unless you spend many thousands. Most of the high end ones are aimed at office scanning, with automatic page feed and high throughout etc. If you're an artist, you're screwed.
Obviously the scanner works on Linux, but my wife is the one who needs to use it. So I hacked together a Raspberry Pi, a heavily customised PHPSane and an ancient Apple iPad (that is similarly unsupported, with almost no software available in the store). The pi boots in about 5 seconds. Now anyone on the house WiFi can scan over the network or walk right up and use the web interface via the iPad which is mounted beside the scanner.
What was really enjoyable about the project was that I got to use one of my old Pis and a tablet that was heading for e-waste.
