2.2 Interfacing to the Printer
Depending on your application, the Printer can be set up in different
ways. Table 2-1 lists the interface cables that should be used for
each situation. If your application is not listed below, refer to
Appendix E which contains interface cable information necessary to
connect the Printer to virtually any ASCII device.

Table 2-1 Interface Cables
For most applications, the interface between the Printer and host
device will be RS-232C. The cable necessary to connect the Printer
to the host will be either a straight cable or a null-modem cable. This
cable connects the DB-25 connector labeled ‘Serial Port’ on the back
of the Printer to the serial data connector on the host device.
The pin configuration of the Printer for most descriptions of the RS-
232C interface on a DB-25 connector is DTE (Data Terminal
Equipment). Pin 2 is transmit, pin 3 is receive and pin 7 is ground.
The Printer supports both Xon/Xoff and CTS/DTR handshaking.
Whenever the Printer is interfaced in a mode that does not use the
CTS/DTR pins, a jumper should be placed on the PC side of the
cable between pins 4 and 5 (CTS/RTS) to bypass the operation of
those control lines. A custom cable must be obtained for this
purpose.
