NOTE: Not all personal computers support all baud
rates. Make certain that your host system will support
your
VARIABLE COMM parameters. Setting the printer
for a baud rate that your host will not support will cause
a break in communication that may be difficult to
remedy.
CognitiveTPG printers will not support all possible
parity, word length, and stop bit combinations. The
acceptable combinations are: N,8,1 or N,8,2 or O,7,1or
O,8,1 or E,7,1 or E,8,1.
Comments When enabled, robust XON/XOFF handshaking
causes the printer to send an XON character once
per second while it is ready to receive data. The
printer will send an XOFF character for every
character that overflows the printer's input buffer.
Enabling robust XON/XOFF handshaking also
enables double-buffered input, which allows
simultaneous label processing and data reception.
However, the double-buffered input reduces the
image buffer size by 4 KB, thus slightly reducing
the maximum label length. Also, you cannot print
PDF417 bar codes with double buffering enabled.
Robust XON/OFF is normally disabled. A lowercase
"r" character will print on the printer confidence
label if robust XON/XOFF is enabled.
For printers having both serial and parallel ports,
connect the host computer to the printer's parallel
port when using the VARIABLE COMM command.
You can use the printer's serial port if the printer or
host does not have a parallel port, but the host will
lose communication with the printer when the
serial port parameters change. Set the new
parameters in the host after you change the printer
parameters.
