not sure if this is the right place for this, but I am new here. we bought a lenovo Thinkstation S20 and we have a Color Laserjet 2550L, when printng from word or excel it prints right away, when printing from a pdf file, it takes for ever, the computer defaults to a 2550 PS Printer, we tried installing the 2550L but it keeps defaulting to the 2550 PS. we have the disc. for the 2550L, but it does not have the option of the windows 7 O/S. help my Boss is going crazy.
