There are fonts built into the ImageWriter II ROMs. They are very simple
character fonts with limited quality. Because these fonts are resident in the
printer, they can print very quickly compared to the bitmaps sent to the
ImageWriter for Faster or Best modes. With a Macintosh, the built-in fonts are
used only when printing in Draft mode or when an application bypasses the
Macintosh print driver.
Draft mode allows very fast printing of documents, giving a best-guess layout
of characters and lines. Because this mode uses the built-in fonts, it cannot
duplicate the spacing and effects visible on the Macintosh screen and is,
therefore, not intended for anything other than rough drafts.
The best way to improve the print layout with Draft mode is to use a screen
font that approximates the ImageWriter fonts used. The ImageWriter fonts are
pica or elite in various sizes between 9 and 17 characters per inch. A list of
the fonts used is on page 74 of the "ImageWriter II Owner's Manual."
Matching different screen fonts to printer fonts requires experimentation.
Because Draft mode was not designed for optimal appearance, use it only for
rough-draft output.
