This problem is usually caused by the Manual Feed option not being selected
in the Print dialog box. The printer assumes that it should not do a
backfeed, and increases the top margin on each page. (Also be sure that
the DIP switch 2-8 is set to Open.)
There is something else you might try: Select the Macintosh Print dialog
box by holding down the Shift key while selecting Print from the File Menu.
This allows you to use the Macintosh print drivers. When you select print
without holding down the Shift key, you are accessing the application's
print driver.
