User-defined Characters
If you define characters in one mode, then switch to another mode and
select the user-defined character set, the command is ignored and
nothing is 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 memory. When 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.)
