Appendixes
The point size of a font is defined as the distance from the top of
the tallest character in the font to the bottom of the lowest charac-
ter in the font. Due to the definition of point size, different fonts
printed at the same point size may appear quite different in size.
This is because there are other font parameters that affect how the
font looks. However, the point size of a font is an excellent specifi-
cation of the relative size of a font. The following examples illus-
trate two very different proportional fonts at 18 point:
ITC Avant Garde abcdefghABCDEFGH
ITC Zapf Chancery abcdefghABCDEFGH
Symbol Sets
A symbol set is the collection of alphabetic and numeric characters,
punctuation, and special characters available in the font you select.
Symbol sets support the requirements for different languages or
specific applications, such as math symbols used for scientific text.
In PCL emulation, a symbol set also defines which character will
print for each key on the keyboard (or more specifically, for each
code point). Some applications require different characters at some
code points. To support multiple applications and languages, all
printer models have 78 symbol sets in PCL emulation.
