GENERAL INFORMATION
1.1 Overview
This chapter contains an overview of the LG31 300 LPM Line Matrix
Printer (hereafter referred to as the LG31 printer). It includes a brief
description of the printer and listings of the electrical, mechanical, and
operational specifications.
1.2 General Description
The LG31 printer is a line matrix printer incorporating a serial I/O (see
Figure 1–1). The LG31 printer uses fan-folded, tractor-fed paper stock,
and operates at 100-240 volts, 50-60 Hertz (Hz). The printer is primarily
used in data processing and office environments, and can be operated by
non-technical users. The LG31 must be installed by a trained Field
Service engineer. It is maintained and supported by Digital Equipment
Corporation.
The hardware environment for the printer consists of all the electrical
and mechanical interfaces. The electrical interfaces are the host com-
munication port, and the ac power inlet. The mechanical interfaces are
the platen gap, paper thickness adjuster, the paper path/tractors, ribbon
cartridge, and the outer/inner control panels. The printer is compatible
with low to mid-range PDP and VAX systems.
No specialized software is required. For data exchange with the host
computer, the LG31 has an RS-232-C port.
