AXIS AX-3 Cobra+ User’s Manual 43
Byte 3 is the Character Spacing in units of 1/720 inch.
‘$3C’ gives 720/60 which equals 12 CPI. For proportionally
spaced fonts, byte 3 sets the width of the space character.
Byte 4 is the ASCII Character Set.
The value ‘$00’ activates the Character Set selected in the Basic
Configuration.
Byte 5 and following.
All bytes after the fourth byte is the Font Selection Sequence that is
sent to the printer to select a font. In the above example it contains
a sequence to select the typeface Courier in the printer (see HP
LaserJet manual).
The Font Selection Sequence does not need to contain a pitch
selection sequence.
Since the AX-3 Cobra+ uses the printer’s own fonts, some of the
predefined FGIDs will result in the same font being printed (see page
75 for a list of predefined FGIDs). To get access to more fonts you can
use external font cartridges for your printer. It may also be necessary to
change some Font Selection Strings to make the AX-3 Cobra select the
fonts you need.
Edit a Font Selection
String
All 50 predefined Font Selection Strings are fully editable. You can,
for example, define new FGIDs, change Character Spacing and
modify Font Selection Sequences.
Example (HP LaserJet):
To change the translation of FGID $0055 from Courier 12 CPI
to Elite 12.2 CPI.
