Xubuntu is a version of ubuntu linux that is good for low end systems. I am typing this entry from such a system. It is a PII 266, Micron Transport TREK II laptop with xubuntu installed on it. Anyways, I was confused when I was trying to add my network printer to the system setup. So instead of pulling my hair out I installed Gnome CUPS Manager like this...

sudo apt-get install gnome-cups-manager

This installed the "Printing Manager" item in the Accessories menu
