That why I suggested using nmap. If it can see CUPS when run from the login where you run WINE, then you'll have verified that the problem is not with your OS. Another way is to use netcat (known as nc in some incarnations). If you do 'nc' to the printer, you can see what happens: $ nc localhost 631 $ [socket closed straightaway] This means CUPS isn't listening or has some other error. $ nc localhost 631 [you don't get a prompt straight back] Hello world [you get an HTML page back reporting a 405 error] $ This means that CUPS is alive and listening to port 631.
