Nope! Just two characters in the download set. This is inconve-
nient for a couple of reasons. First, every time you wanted to
use a download character
you would have to switch back and
forth between character
sets. Knowing that you wouldn't want
to do that, your printer won't even allow it. So we have made it
an easy task to use mostly standard characters
with just a few
special characters
thrown
in. This command
copies all the
ASCII
characters
from
the standard
character
ROM into
download RAM:
(ESC) ":" CHR$(O) CHR$(O) CHR$(O)
Since it will copy all characters
into download
area, it will
wipe out any characters that are already there. So it's important
to send this command
to the printer
before
you send any
download characters
you want to define. With that in mind, add
this line to the program we used to send the characters
to your
printer:
5 LPRINT CHR$(27) ;": *'
;CHR$(O);CHR$(O);CHR$(O)
Now try the download
printout
test program
again. Your
results look like Figure 8-9.
Figure
8-9. Printout
of the download character
set, into which all
the
ASCII characters have been copied, and the ( and = have been
changed.
