Programmer’s Notes
When the serial port is being used, it is important that the output lines from the printer not be shorted
or back driven. If the signals are not to be used, they should be left open.
Pins 3, 4, and 7 are outputs from the printer. If any one of these signals is grounded or back driven,
the other two outputs will be degraded.
The best time to configure the printer by the host is during system setup or software update.
The printer should be power cycled after configuration to assure that the new configuration takes
effect.
In serial mode, one-line mode should be avoided, particularly in XON/XOFF mode. The high speed
FIFO input buffer makes one-line mode difficult to process.
If the knife module fails at any time, the configuration can be changed to deactivate the option and
the printer will not ask it for status. This will allow the printer to be used without the option until the
printer can be repaired.
