User-defined Characters
Mixing print styles
Each of the three user-defined character modes (draft, Letter
Quality, and proportional)
can
be used in combination with
most of your printer’s various print styles. For instance,
emphasized works with user-defined characters. The characters
you design are enhanced to give this printing effect.
Mixing the types of user-defined character sets is not permitted.
If, for example, you select draft and define some characters,
then
select proportional and define some more, the first
character definitions will be destroyed. Only one type of
character definition may be stored in RAM at
any
time.
If you define characters in one mode, then switch to another
mode and select the user-defined character set, the command
will not be effective and
the
character in ROM will printed.
The user-defined character definitions, however, remain
unaffected. If you switch back to the mode in which they were
defined, you can then select and print them.
Keep in mind that user-defined characters are stored in RAM,
which is not permanent. Whenever the printer power is turned
off, or the printer is initialized with the INIT signal, the
user-defined characters are lost. (Some computers do this each
time BASIC is loaded.) ESC @, however, does not destroy
user-defined characters.
