Defining user-defined characters
ESC/P 2 ESC/P 9-Pin ESC/P
With the user-defined character function you can design your own characters
and save them in the printer’s memory for repeated use in a print job.
The printer has two types of character memory: ROM and RAM. The printer
stores its built-in character sets in ROM memory; you cannot modify ROM
memory. You can modify RAM memory, however, in two ways: you can copy
characters from ROM memory and you can save user-defined characters.
The general method of defining characters (sometimes called downloading) is
basically the same with all EPSON dot-matrix printers. However, the method of
accessing user-defined characters depends on the ESC/P version. This section
explains the basic process while describing the differences when necessary.
Note:
You can only print user-defined characters as 10.5-point characters (or 21-point
characters when double-height printing is selected). Even if you select a different
point size with the ESC X command, characters in RAM can only be printed as
10.5 or 21-point characters.
The steps below should be followed to create user-defined characters.
1 Plan the data for your desired characters. The amount of data required
depends on the following factors:
The number of dots in the print head (9 or 24/48)
The space you specify on the left and right of each character
Character spacing (10 cpi, 12 cpi, 15 cpi, or proportional)
The size of your characters (normal or super/subscript)
The print quality of your characters (draft, LQ, or NLQ mode)
2 Cancel italics with the ESC 5 command and set the following traits of the
characters you plan to define:
Print quality
Size (either normal or super/subscript)—24/48-pin printers only
Proportional or fixed character spacing—24/48-pin printers only
