B.1.2 PRINT TICKET MODE
The Print Ticket Mode is designed specifically for a serial printer. Figure B-3 shows the fixed
format of the print ticket.
For printers with limited buffers, this mode supports DTR pin handshaking by enabling A7 in the
User Menu. The DTR pin from the serial printer is wired to the indicator’s RXD pin
which then functions as a CTS pin. Figure B-4 shows a suggested cable diagram
for interfacing to a serial printer. Refer to the printer’s user manual to confirm
whether or not it supports the DTR pin. The cable depicted in Figure B-4 can be
used even if the printer does not support the DTR pin.
