Datamax ST-3306, SV-3306, ST-3210, SV-3210 manual Interfacing the Printer

3.1Interfacing the Printer

Interfacing the printer to the host computer can be made through either a parallel or a serial cable (see Appendix C for cable requirements). Communication port selection is automatic: the first port to receive data is set ‘active’ by the printer. To change an active port, cycle the power ‘Off’ and ‘On’ or perform a Warm Reset (see Section 3.6.1).

Parallel Interface Port:

The parallel interface supports Centronicsâ parallel communications.

Serial Interface Port:

The serial interface supports either RS-232 or RS-422 communications. The following menu-selectable serial port settings must be configured to match those of the host computer; see Section 4.3.

∙Baud Rate

∙Word Length (including Parity, which defaults to either of the following):

8-bit word with no parity

7-bit word with even parity

þ Note: If unable to establish communications, see Section 5 for help.
