Parallel Data Communications

The table below illustrates the pin connections on the Bi-directional Parallel connector at the rear of the printer.

Parallel Interface

The 8-Bit Parallel Data Interface supports IEEE 1284 bi-directional parallel communications in “nibble mode”. The parallel interface provides a means of communication which is typically faster than the previously mentioned serial interface methods. In this method, the bits of data which make up a character are sent all at one time over several wires in the cable, one bit per wire.

Parallel Cabling Requirements

An IEEE 1284 compatable bi-directional parallel data cable is required when this communication method is used. The required cable must have a standard 36-pin parallel connector on one end which is plugged into the mating connector located at the rear of the printer. The other end of the cable connects to the printer connector at the host computer.

Note: The printer does not support Enhanced Parallel PC bios settings such as ECP and EPP. Make sure your PC is configured to Standard AT or similar standard parallel mode.

Also- If you experience issues where a print jobs fail to complete and after cycling power the job starts from the beginning try increasing the Window LPT port timeout. This is under Properties for the LPT port. Default is typically 90 and the suggested increase is to set it to 190.

Once attached, test by sending a ZPL label format. (This must be a Zebra Programming Language (ZPL) label format or the printer will not respond.) ZPL can be written as a simple text file as shown in this example, created using a Zebra Driver in a Windows application or a label software that is compatible with the Zebra printer.

Example ZPL format:

^XA
^FO20,20^AG^FDTest^FS
^XZ
