Connecting the
Parallel Interface
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.
Connecting the
Power Cord
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.
OEM
Configurations
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).
