Drivers are from the cd provided by Lexmark (ver 1.01 i think) and I recently updated the printer's firmware as well.
Glad you got it solved and it was that easy.
FWIW, I seldom, if ever, use the printer drivers that come in the box with a printer. If OS X does not already have a driver for the printer, I will go to the manufacturer's website and download the very latest driver version from there. The drivers that come on the disc in the box are almost invariably one or two, sometimes more, releases out of date. That is just a fact of life in the manufacturing and distribution cycle.
