Why does my Lexmark X4550 only want to fax? -

I have followed the instruction guide for my dad s lexmark x4550, installed the driver from the disk and then set up the wireless configuration. However, whenever I want to print, it just tries to fax things! I ve tried several times, but the results are still the same and it s getting really really irritating, so any help at all would be really really helpful!

I have this printer but don t have this problem though...try clicking FILE, PRINT then choose the printer X4550 not Lexmark fax in the options then press print.
