Subject: Epson LQ Color Driver for Microsoft Windows 3.0 and 3.1
Date: 4/3/92 PSB No: P-0087

Page(s): 1 of 3

The purpose of this bulletin is to announce the availability of an additional color
driver for the LQ-860, LQ-2500, and LQ-2550 for the Microsoft Windows 3.0 and

3.1 environments. This driver is primarily intended to provide Device Independent
Bitmap (DIB) support for Windows based application software. The most popular of

these is Paintbrush which is included with Windows 3.0 and 3.1.
When upgrading to Microsoft Windows version 3.1, it is recommended to use the

Epson driver that is included with that version of Windows. The Microsoft Windows

version 3.1 drivers have DIB support built-in, in addition to new enhancements.

NOTES

The LQ-2500 is only supported with tractor paper. This is because in single sheet

For best results you should print at 360 x 180 DPI for normal printing and 180 x
180 DPI for draft printing.

Error 11 indicates that the paper is not straight.
Error 12 indicates that the paper was loaded using the platen knob instead of the

LOAD/EJECT button.

When these errors occur, the printer stops, the audible alarm sounds, and one

of these two error messages will appear on the front panel.

Sound intensity is measured in units called Bels (named after Alexander Graham Bell,)

or more commonly in tenths of this fundamental unit: decibels. In making noise
measurements a weighting network is applied in an attempt to match the frequency
response of the instrument to that of the human ear. The most common is the A

weighting network, with resulting measurements expressed in dB(A).
The following is a list of current product’s noise levels tested in accordance with

standards set by the International Standards Organization (ISO). The acoustic noise

levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ)
mode using continuous paper and are not guaranteed figures. The acoustic noise
levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode
using continuous paper and are not guaranteed figures. The acoustic noise levels for

the laser printers are averages while using single sheet paper and are not guaranteed
figures.
