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
the LQ’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 three types of user-defined characters 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 be
ignored and nothing will print. 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 intialized with the (INIT) signal, the user-defined
characters are lost. (Some computers do this each time BASIC is
loaded.) ESC @ does not destroy user-defined characters.
