Thanks for providing. Installed it this week and scanning/printing works both via USB and via network/CUPS (after adding the printer as described in the pinned comment). Unfortunately this package doesn't include drivers for the fax which I have yet to find a solution for yet.
I'm using a Steam Deck which by default lacks the KDE parts for managing a printer. But installing the package 'print-manager' with pacman fixes this and now I can administrate the printer via the system settings too.

Thanks for adding this to the AUR.
To print from my system, I had to add the printer in CUPS as a 'LPD/LPR Host or Printer', and my connection is 'lpd://PRINTER_IP/BINARY_P1' substituting my printer's ip address for PRINTER_IP. Hope this helps someone else.
