Apple 12/640PS manual How the Mac OS looks for fonts, TrueType and PostScript fonts

TrueType and PostScript fonts

PostScript fonts were designed as fonts for PostScript printers. However, if you have Adobe Type Manager software installed, your computer can both display and print PostScript fonts.

Use different names: To avoid confusing the printer software, be sure that you don’t install both TrueType and PostScript versions of the same font. For example, do not have a PostScript font file called Times and a TrueType font file called Times installed in your system at the same time.

How the Mac OS looks for fonts

Here’s the search order the Mac OS uses to determine which font to display on your screen when you choose a specific size:

1.an installed bitmapped font in that size, if one exists

2.a scaled TrueType font, if no bitmapped font exists

3.an Adobe Type Manager (ATM) version of a PostScript font, if ATM is installed and if no TrueType version exists

4.a scaled bitmap if no ATM font exists

Here’s the search order it uses to determine which font to print on your

LaserWriter 12/640 PS (or any PostScript printer):

1.the printer’s ROM

2.the printer’s RAM

3.the System Folder where it looks first for a PostScript version of the font, then TrueType, and finally a bitmap version.
