Cups - is it installed and running? Easy way to tell, open a web browser, type 'http://localhost:631' This should load the cups configuration and management page. If you get page not found, then either cups is not installed or not running.
Open a console, run this command '/sbin/lsmod' (without the quotes) and post the results. That will tell us what modules you have loaded.
