slackware 9.1 comes with cups.
you will want to run it by becoming root and typing /usr/sbin/cupsd to start the daemon
then go to http://localhost:631/admin
you will need to log in as root on the site
once you have the printer installed edit /etc/rc.d/rc.local and include the line : /usr/sbin/cupsd
this will start the daemon everytime you log in
hope this helps. let me know when you get it set up.
