If you go into the cups web control panel at

http://localhost:631/printers/?

if it is on the local machine

or

http://WHATEVER_THE_CUPS SERVER_NAME_IS:631/printers/?

if it is on another machine

THEN:

select the appropriate printer and you should see a

Connection socket://address

which would be the address of the printer


As an alternative you can try:

sudo grep PRINTER_QUEUE_NAME /etc/cups/printers.conf

on the machine running cups


Hope this helps
