computer using universal control commands. You can then specify up to
128 custom characters.
Even if you do not intend to download custom characters, minimizing the
input buffer to 532 bytes has some side-effect advantages. Consider
minimizing the buffer size to minimize:
Data loss due to possible power, network, or computer failures
Dedicated computer-to-printer transmission time
Note
: Storing downloaded characters does not activate them. After you
download a character or characters using universal control
commands, you must "map" them into the active character set
using still other universal control commands or the "Accept User-
Defined Characters" setting (Page 90) under "Overlay Characters"
in the configuration menu. Only then does "Print Active Character
Set" (Page 54) and "Print Data Byte Map" (Page 61) reveal the
character substitution(s).
