help with lexmark printer

Can some one help me resovle the print sever error i keep getting with my
lexmark printer in vista for some reason the drivers that came with the
printer are not for vista and they locked out any attempt to remove them
totally or to install a differnt printer or newer one from there web site.
The man at the store said it `s an easy fix but they have to charge me. The
whole package is only a week old.But i can`t get it to work so my only
optoin is to return the whole thing as a defect. Can some one please help me
thank you very much
