How to get an M2 Mac mini printing to a Canon MP990 Printer with Ghostscript/Gutenprint?

I bought a new M2 Mac mini, my first Apple Silicon Mac. The Canon MP990 Scanner still scans fine with VueScan, but printing now fails. I'd set up the Intel Macs with Gutenprint (I use HomeBrew for as many installs as possible) which worked fine with them and I'm running Ventura (same as my former Macs). I’m *avoiding Rosetta* because I want to set this up to be as future-proof as possible. So I installed Gutenprint on the M2 MacMini with Homebrew (fresh M2 install), then tried to set up the printer (USB connection) but had to use the CUPS settings at http://localhost:631/ to add it and assign a "Generic PostScript Printer" driver (System Settings doesn't offer a generic driver). I also installed Ghostscript (a stab in the dark) and generated a "Generic GDI Printer" Ghostscript .ppd file at OpenPrinting (an interesting resource), put it in /Library/Printers/PPDs/ but it was rejected (presumably not for Apple Silicon Macs and/or not 64 bit) when I chose it in the printer setup. The printer now appears under "Printers & Scanners", the job goes through (a PDF, very slowly) and the printer queue becomes empty. However, nothing gets printed and the printer shows as "idle". Has anyone managed to get an older Canon printer working? There are a few success stories, but nothing beyond what I’ve tried. **UPDATE:** I just spent 3 days on this, having tried every possible solution both suggested here and out there, with no luck. I’m now considering a new laser printer. The scanner still works with VueScan, though…
