Show HN: I reverse-engineered the driver for my 15 year old printer (Dell 1320c)

[biosed]

I have a Dell 1320c, I've had it for 15 years, but the drivers stopped getting created many many years ago. It was sort of working in OS X but will stop when rosetta 2 goes away. I'm running Linux on an M1 mac and no driver support for aarch64. It has an old i386 CUPS driver, I used it and with some help from AI got byte perfect matching in the stream. It uses some proprietary compression called SQ21. Anyway, I now have clean C for the whole chain and so a native driver in Linux aarch64. I've now used that driver on a Pi Zero to have wireless printing. My colour laser lives again!
