lemark driver install issue on xp

installed xp on a dell laptop a week ago. Bought Lexmark
X5270 printer with usb. Install seems to work ok and I
have the programs for the printer, but have the
error "required section was not found in INF" and is says
the driver was not installed.

Also saw a reference to Windows not being able to find
C:\windowsystem\spool\drivers\w32x86\3\lxbtpxwx.ex e file
at one point.

Have tried unistall/reinstall--same issue every time with
the INF comment and driver issue.

Any ideas???
