A Special Note for QuarkXPress Users

Make sure you have installed the QMS 1660 and 1660E PDFs in the PDF folder in the QuarkXPress folder. While QuarkXPress 3.3 allows you to access either a PDF or a PPD, to have access to all of your printer’s features, you should use the PDF. To select the PDF, go to the Page Setup dialog box in QuarkXPress, and hold down the Shift key while clicking the Printer Type list box. (The italicized selections are PPDs, and the non-italicized selections are PDFs.)

»Note: The 1660E PDF allows you to choose between basic and enhanced (advanced) screening (or halftoning) in QuarkXPress. If this PDF is not present, you won’t be able to used enhanced halftoning even though the printer supports it.
