PQ-8P, PQ-8S

2. Introduction

The PQ-8P and PQ-8S are powerful, yet easy-to-operate external printer interfaces. The PQ-8 can easily be set up through on-board DIP switches, Host/PC download commands, or the setup software.

The PQ-8P and PQ-8S attach virtually any ASCII printer to an AS/400 or System/3X host. They offer reliable emulations of IBM 3812, 4214, 5224, 5225, and 5256 printers. When connected to a laser printer operating in PCL® mode, the PQ-8 allows Computer Output Reduction (COR) and Automatic

Print Orientation (APO). In addition, paper can be pulled from several sources, jobs can be printed on both sides of the paper, and a multitude of fonts (printer-resident or from optional cartridges) are supported.

The PQ-8P comes with a standard parallel sharing port that allows automatic sharing of the attached printer between the host and a PC or LAN. The PQ-8S comes with a standard serial sharing port.
