Thanks for the help guys. To resize my screen I had to go through the GUI part and change it but unlike Microsoft it makes me reboot in order for it to take affect which sucks. The Ctrl Alt +/- does not work.
As for adding a printer someone finally gave me the link to the correct document which showed how to do it. I received a link where you can download the CentOS manual in PDF format: http://www.centos.org/docs/4/pdf/ but the guy didn't tell me which manual I'm suppose to download. I cant tell what's what by the name so unless someone here can point me in the right directions I'm still waiting on their response.
