Proportional Width Table
This table lists the widths of your printer’s proportional characters. The
values given are in 360ths of an inch. For example, a value of 36 is
36/360ths of an inch. You may need to enter these widths into a special
table for your processing program so it can calculate the number of
proportional characters that will fit on a line.
The characters with no code indicated are international characters or
graphics. See the table in the section on international characters in
Chapter 3 for the relevant codes for the international characters. Also,
see the descriptions of the ESC R and ESC t commands in the Command
summary (Chapter 8) for information on how to use these characters.
The following width table shows each character, its ASCII code
(hexadecimal), and its width. If there are two numbers in the width
column, the second one is for the superscript/subscript version of the
character.
