Understanding Fonts 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 character 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 specification of the relative size of a font. The following examples illustrate 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. 332 Understanding Fonts
