What good is a desktop PC if it can't print?
Here are some simple steps to get the above printer and many others working since the gutenprint package contains support for a lot of printers by various vendors such as Cannon, Brother, HP, Dell ......
See the below link for a full list of supported printers.
Open a terminal and with root access type the following,
emerge -av cups gutenprint
rc-update add cupsd default
KDE users can now configure their printer using System Settings > Printer Configuration
Or if you prefer the cups browser interface, http://localhost:631
