All of these resolutions are single pass 8 pin modes with no interlacing.
|
|
The IBM QuietWriter III has a 40 pin thermal printhead, but only 8 pins
|
|
are used in graphics mode.

|
|
The default CTT is CP437. Thius is necessary because the embedded fonts
|
|
are all CP437 and it is necessary to select both the font and code page
|
|
for font selection. I used the Courier 10 CPI as the default font. The
|
|
driver also uses an x-move command that requires setting the printer into
|
|
a known CPI state. As a result, all font de-select commands use the
|
|
ESC[T command to set the printer to CP437.
|
|
|
|
The printer cannot do italic print from normal fonts. Special italic fonts
|
|
are required to do the italic text.
|
|
|
|
Since fonts are called by an ID number, it is transparent to the printer
|
|
whether the font is embedded, hardwired cartridge or Downloaded into the
|
|
cartridge. As such, all fonts use the same commands independent of source
|
|
so some font files are used for several modes.
|
|
|
|
If the font is a download font, the font must be loaded into the font cartridge
|
|
from DOS before running the Windows app. The driver does not support
|
|
on-line downloading of fonts. (This is compatible with the 3.0 driver.)
|
|
|
|
The driver is set up to feed paper from:
|
|
Tractor Feed
|
|
Cut Sheet Feeder Auto
|
|
Cut Sheet Feeder Manual
|
|
|
|
Only the tractor feed option has been tested.
