I'm only looking to get the printer part working. I have set up the scanning part to scan to an CIFS drive on the printer itself. I used to use the fax capability, but nowadays everybody just accepts scanned PDFs via email, so that feature is not of importance.
The printer is a relabeled Xerox 6000B, but Xerox only provides 32bit i386 binaries and my system is now amd64. This doesn't bode well for a future setup.
Installing the printer driver binaries
After installing CUPS, the magic printer driver is
apt install printer-driver-foo2zjs
Configure it for the network
Location: 192.168.1.xx Device-URI: socket://192.168.1.xx:9100 Model: Dell C1765 Foomatic/foo2hbpl2 (recommended)
Using that printer driver, I get feedback on the toner fill and can print in color.
Configure the printer on the computer
Enter the printer settings
Set color mode from "monochrome" to "color"
I had to reset the number of pages per sheet from 9 to 1. Most likely this was a manual misclick by me first.
Print a test page
Just to be sure, print a test page. For me, the printed configuration text reads:
