I supose that is a dumb question, but Im a novice in Linux. > Check the access permissions on the parallel ports: ls -l /dev/lp* If Ubuntu is like Fedora, only root and the lp group have access to parallel ports. There are two things you can do. Pick either: 1) add the user where you run WINE to the lp group 2) add the command line chmod uga+rw /dev/lp*" to the /etc/rc.d/rc.local system script. You'll have to be root to do that. Doing this will give all users read and write access to all parallel ports each time you boot the system. I'd suggest you try (1) first, since is less drastic than (2). Martin
