Hi! I think you must set up the serial port of your printer. Try these commands in a terminal as root: stty 230400 raw -echo cstopb </dev/ttyS1 stty ixon ixoff </dev/ttyS1 S1 or S0 are the ports to one of them your printer is connected. Try cups. If it works put a file named local in /etc/init.d/ and update your system with rcconfig.
Hope this helps. Suse has a support database where you can find more if you need. Ciao Chris.
