Adding fonts to a PPD file
The Font Configuration dialog box lists both system fonts and
PPD/Installed fonts for your software program. The system
fonts are the fonts currently installed on your system. The
PPD fonts are those included in the PPD file of your software
program. These fonts are automatically downloaded as needed
when you send a print job.
You can add any font on your system to a PPD file simply by
selecting the system font and then choosing the Add button.
The system font is then displayed in the PPD list.
If you install any new fonts on your system and you want
those fonts accessible from your software program, you should
add them to the PPD list.
To remove any fonts from the PPD list, simply select the PPD
font and choose the Remove button
Substituting fonts
When you turn on Substitute Fonts and then print common
Macintosh screen fonts (Geneva, NewYork, and Monaco),
EpsonScript automatically substitutes one of its fonts. This
results in faster print speed and higher resolution. Be aware
that if the substituted font is significantly different from the
screen fonts, the printed output might look very different from
the way it looks on screen. For this reason, you normally
should not turn on Substitute Fonts.
