When printing from MacDraw II (all versions), if Larger Print Area is enabled in the Page Setup Options dialog box, the top 1/8" or so won't print. The only workaround is to disable Larger Print Area, or to print to a different printer, such as the LaserWriter IINT/NTX.
MacDraw II gets its information about the printable area from the LaserWriter driver. However, not all printers can print to the maximum printable area that's defined in the print driver.
