PRINTING DOWNLOAD CHARACTERS
You’ve now defined and sent two characters to your printer.
But how do you know that? If you try printing those characters
now you don’t get a car and telephone. Instead you get . . ( = .
That’s because the download characters are stored in a different
part of the printer’s memory. To tell it to look in download
character RAM instead of standard character ROM it requires
another command:
(ESC) “%” n
Where n is either 1 (to select), or 0 (to cancel). If you want
your new characters to be included in a standard character set,
you may copy the standard set stored in ROM into the download
RAM, which will save you switching back and forth between
the download area and the standard ROM. If you wish to use
this option, make sure that you copy the standard characters in-
to RAM before you download your own, because the last-
copied characters replace previously copied ones. The com-
mand to copy the standard characters into the download RAM
area is:
