3-8 Font Basics
Symbol Set
ESC(ID
Each symbol set contains characters and symbols which are used for specific
purposes. The printer supports special character sets for technical, legal and foreign
language purposes and additional character sets for graphics. Each font uses standard
symbols, as well as symbols from one or more of these sets.
Examples:

Spacing
ESC(s#P
This ESC sequence determines the spacing of the printed document. # may have one
of the following values:
Value
0
1
-1
Some fonts have fixed spacing, i.e. the amount of space allotted to each character is
uniform. Other fonts are proportionally spaced i.e. narrow characters such as i are
allowed less horizontal space than wide characters, such as w.
Pitch
ESC(s#H
This ESC sequence determines the print pitch. # represents the pitch in characters per
inch (cpi). For example:
10 cpi
16.66 cpi
This command is used only with fonts of fixed spacing. The pitch is the measure of
the character width, i.e. it represents the number of characters per inch (cpi). The
larger the number of characters per inch, the smaller the character.
A field value of up to two decimal places is acceptable here.
