Printer Commands
4 Enable Power ON TOF: This bit controls whether or not the printer will
do an automatic Top Of Form (TOF) when it is turned ON.
5 Enable Button TOF: This bit determines whether the GREEN button
functions as a Top-Of-Form or as defined by SW#2 bit 4. The button is
always configured to clear error conditions.
6 Enable AutoLoad: This bit determines whether the AutoLoad function
is ON or OFF. When Autoload is enabled, and a no media to media
transition is detected by the printer's internal transmissive sensor, the
printer will step the pulled the media into the printer and perform either
a TOF or a Form Feed depending on SW#5 bit 7 configuration.
7 Type of AutoLoad: This bit determines whether the AutoLoad function
uses the Top-Of-Form sensor (TOF), or if it uses the Form Feed
technique.
8 Status Byte Mode: If enabled, the printer will enter a special mode that
sends a status byte to the host. See D110 command

^AB ^D COMMAND
XX 26 Change SW6: Software Switch #6.
^AB12345678 (each bit is represented by a numeric position number)
Position:
1 Enable >TRAY FULL< response: This bit is used to define whether a
test pattern will print, or if the printer will halt on a >TRAY FULL< error
condition when the printer is used with the optional catch tray on the
Model 424 printer. This bit will also determine the printer's response
when pin 4 of P17 is active.
2 Enable STL Emulation: This bit determines whether the STL
emulation is enabled or not. This command provides similar
functionality of other printer manufacturers that specify exact placement
and location of blackline media used for registration. The printer takes
in STL commands and internally converts them to LDS command
tables.
