Welcome to the forum nilmarins.
Maybe a stupid question BUT what kind of printer is it? Brand and mark... Is it supported by Linux?
Have You tried using KMenu > System > Configuration > Configure Your Computer...
In there go to Hardware section and Click on Set Up Printer button. Follow the wizard and You should be able to setup a printer from there...
If in the hardware section there is no Set Up Printer button go to Synaptic Package Manager and install package called printerdrake.
After reboot this option should appear in PCC (PCLinuxOS Control Center).
Hope this helps
