Page B-27APPENDIX B — SCS/DCA COMMAND SUMMARY
Command: Set Character Density (SCD)
Format: 2B D2 nn 29 00 cp
Printers: 3812, 4214, 5219, 5224, 5225
Action: Specifies the character density in characters per inch
(CPI) for subsequent text.
The cp parameter specifies CPI.
For the 4214, values of 00h (no change), 05h (5CPI),
0Ah (10CPI), 0Ch (12 CPI) and 10h (16.7 CPI) are valid.
For the 3812 and 5219, values of 00h (no change), 0Ah
(10 CPI), 0Bh (proportional spacing), 0Ch (12 CPI) and
0Fh (15 CPI) are valid.
For the 3812 and 5219, the value 0Bh (proportional
spacing) is effectively the same as setting the ps
parameter value of the Set FID through GFID (FSG)
command to 02h. For the 5224 and 5225, values of 00h
(no change), 0Ah (10 CPI), 0Ch (12 CPI) and 0Fh (15
CPI) are valid.
This command recalculates the horizontal Maximum
Print Position (MPP). If the newly calculated MPP is less
than the current MPP, it overrides the old MPP setting.
IBMEMUL: Same as IBM.
The OPTIMA supports all CPI values for all IBM printer
emulations.
The OPTIMA, in addition to all of the above values of
the cp parameter, supports values of 08h (8.6 CPI) and
11h (17.1 CPI).
If the current orientation is portrait, one of the PFSs
P 5CPI> (CPI≤5), P 8CPI> (CPI≤8), P 10CPI
(CPI≤10), P PSCPI> (proportional spacing),
P 12CPI> (CPI≤12), P 15CPI> (CPI≤15),
P 16CPI> (CPI≤16) or P 17CPI (CPI>16) will be
sent to the target printer to invoke the appropriate CPI
value.
