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 on page 3-35 for the
relevant codes for the international characters. Also, see the
descriptions of the ESC R and ESC t commands on page 9-37
and 9-36 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.
