User-defined Characters
Therefore, your printer has a command which allows you to
copy all of the standard characters from ROM to the
user-defined character set.
The command format is as follows, where the value of n
represents the font family:
ESC: 0 n 0
Note: This command will cancel any user-defined characters
you have created. You must send this command to the
printer before you define characters.
If you use this command at the beginning of a program,
then
define your special characters and select the user-defined
character set, you can print with the user-defined set as your
normal character set. You’ll never need to switch back and
forth between sets.
Letter
Quality characters
If you select Letter Quality printing with the ESC xl command,
you can design user-defined characters using up to 29 columns
of the Letter Quality/Proportional grid. The dot columns are
spaced closer together horizontally than draft style dot columns
(the
horizontal dot spacing is 1/360th of an inch as opposed to
1/120th of an inch for draft characters).
Proportional mode characters
Selecting the proportional character mode will yield
user-defined characters of the highest resolution. Characters
can be designed using all 37 columns of the Letter
Quality/Proportional grid.
