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.
