Hi, Lexmark Printer Problem HELP!

I installed Norton 360 today and now I cannot use my Lexmark printer, I have tried disabling Norton and rebooting the computer but this does not make any difference. (PS I cannot afford to uninstall Norton and buy something else). The Printer is a Lexmark all in one X1190. Using windows XP.

Can someone please give me good technical advice on how to sort this Please!

Thanks in Advance!
