Disabling Bidirectional Communication

Introduction

Printing problems may occur, and you may receive error

messages when the HP Printing System for Windows is

installed on a computer that does not have a bidirectional port or

a bidirectional printer cable. Printing problems specific to

bidirectional communication (two-way communication) can be

fixed by upgrading your computer's hardware so that it does

have a bidirectional port or a bidirectional printer cable, or by

turning off the bidirectional function in your printer driver

software.

If you turn off the bidirectional communication in your printer

driver, the print quality will not be affected. However, some of the

advanced features of the Status Monitor or HP Toolbox will be

disabled:

You will no longer receive reminders to align the print cartridges

after a new print cartridge is installed.

You will no longer receive error messages associated with the

print cartridges.

You will no longer receive error messages associated with the

banner lever on HP DeskJet 680C, 690C, 720C, 895C, or

880C printers.

This document provides information about how to turn off the

printer driver's bidirectional communication in Microsoft (R)

Windows 3.1x, Windows 95, Windows 98, and Microsoft

Windows NT 4.0. Since the document contains instructions, you

may want to print it for easy reference.

Steps to turn off bidirectional communication

NOTE: The LPT1.DOS port selection does

not support bidirectional communication. This

port setting can be used to eliminate

bidirectional communication in Microsoft

Windows 3.1x. Bidirectional communication

can also be disabled in the Configuration File

by following the instructions below.

1.The starting place is slightly different depending upon the

operating system.

For Windows 3.1: In Program Manager, choose File and

click Run.

For Windows 95, Windows 98, and Windows NT 4.0:

Choose Start and then click Run.

2.On the Command line or Open line, type the appropriate

filename and click OK. Use the following tables to find your

printer and its appropriate filename.

3.Click Continue in the message window.

4.Remove the X next to Print Cartridge Query and the X next to

Bidirectional Communication.

5.Click OK.

6.Click Restart Windows.
