Using an operating system other than those officially supported, printers can be added via CUPS.
Example from Fedora 34:
Find your printer from cern’s printservice webpage. Copy the printer ppd from lxplus and install deps:
sudo dnf install -y cups-lpd system-config-printer
scp lxplus:/etc/cups/ppd/your-printer-name.ppd ~
From here, run system-config-printer and configure a new LPD/LPR printer.
Host: <your-printer-name>.print.cern.ch
Queue: <your-print-name>
then simply accept the rest of the default settings & test print!
