For pinout information, as well as information on how to interconnect to either a DTE or DCE device, refer to the Appendix.

Parallel Interface Requirements

Refer to Figure 6.

An IEEE 1284 compatible bi-directional parallel data cable is required when this communication method is selected. The required cable must have a standard 36-pin parallel connector on one end, which is plugged into the mating connector located inside the access opening on the left side of the printer. The parallel interface cable is connected using bail clips instead of screws.

The other end of the parallel interface cable connects to the printer connector at the host computer.

For pinout information, refer to the Appendix.

Serial and Parallel Cabling Requirements

Data cables must be fully shielded and fitted with metal or metallized connector shells. Shielded cables and connectors are required to prevent radiation and reception of electrical noise.

To minimize electrical noise pickup in the cable:

1.Keep data cables as short as possible.

2.Do not bundle the data cables tightly with power cords.

3.Do not tie the data cables to power wire conduits.

Communicating with the Printer

Via the Parallel Port

nSet the parallel connection on the host computer. For instructions, refer to your computer’s user’s guide.

Via the Serial Port

nSet the host computer to the factory defaults of the printer: 9600 baud, 8 bit word length, no parity, 1 stop bit, and XON/XOFF. For instructions, refer to your computer’s user’s guide.

NOTE: If you can’t reset the host computer communications settings, then you must establish a temporary parallel connection to send down the Set Communications (^SC) command that changes the printer’s settings to match the host settings.

DEFAULTING THE PRINTER: To reset only the communications parameters on the printer to the factory defaults (9600 baud, 8 bit word
