Many different OEM organizations have been integrating Printrex products into combined hardware and software systems; some for nearly 20 years. These complete-solution products may be assembled in closed physical packaging or racks, or may consist of pre-configured computer hardware that is deployed like any other office equipment. Software may be command-line or graphically operated, and might be installed with a Unix-type or Microsoft operating system. Interconnection interfaces include various types of parallel or serial ports, USB and/or Ethernet.

While Printrex has experience in supporting the development of a variety of these OEM systems, it is impossible for us to maintain the information and knowledge necessary to provide detailed support in the operation of these systems. Persons having questions regarding use of a specific product are best advised to consult the documentation or support services provided by the OEM.

For clients directly receiving Printrex products to install as end users into existing or new systems, we wish to make the installation process as trouble-free as possible. Several documents are available for reference which are intended to describe the most common installation scenarios (see the Additional Documentation section of this guide).

First, be sure to use a high-quality cable. The cable should be marked “IEEE-1284” to indicate compliance with this communications standard. Inexpensive cables are electrically inferior and can result in unnecessary communications errors.

Connect the 25-pin connector end of the cable to the parallel port of the computer. Use the screw locks to secure the cable, but do not tighten excessively.

Make sure the printer power is off, then, plug the Centronics 36-pin connector end of the cable into the printer and engage the spring clips to lock the connector.

Avoid making any other connections between computer and printer, whether to add extension cables or to install daisy-chain disk drives or scanners. Integrity of communications is greatly degraded when these items are in the signal path.

For other installation and connection options, please refer to the Printrex System Administrator’s Guide.

First turn Power Switch to the off position (the off position is shown by the international symbol “O”). Connect the IEC female end of the cord to the power connector on the rear of the printer chassis. Plug the male connector into a properly grounded three- pin AC main power outlet.

Do not use a “cheater” connector in order to use an inexpensive two-wire outlet or extension cord. This defeats the grounding protection of the product and may introduce a serious electrocution hazard in wet environments.
