User-defined Characters
Copying ROM Characters to RAM
After running the program, if you select the user-defined character set
and try to print other characters, the only one that will print is your
arrow. Since no other characters are in the printer’s user-defined RAM,
there is nothing else to print. Other characters sent to the printer do not
even print as spaces; it’s as if they were not sent at all.
In many cases, you will want to redefine only a few of the characters to
suit your needs-the rest of the alphabet will work fine as it is. As you
have seen, it is possible to switch back and forth, at will, between the
normal character set and your user-defined character set. It is, however,
rather inconvenient.
Therefore, your printer has a command that 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:
E S C : 0 n 0
Note:
This command cancels any user-defined characters you have
already 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 set, you can print
with the user-defined set as your normal character set. You never need
to switch back and forth between sets.
