Hello Greg, Perhaps, try:
GUI: avahi-discover from the avahi-discover package presents a network tree: you can find the IP adresses of the printers CLI: # avahi-browse -r _print-caps._tcp (from the avahi-utils package) In my case it's sufficient to detect my network printer but I do not know well avahi service types (here: _print-caps._tcp, seems to be printer capabilities at the TCP level) if you do not find your printers try a more general search: # avahi-browse -avr and explore the results
