When you print to a Hewlett-Packard (HP) printer (or a printer that
emulates an HP printer) that is connected to a computer using a PS/2-style
parallel port, you may receive an extra page before each print job. The
extra page contains PJL codes or a single character in the upper left
corner of the page. The output on this page depends on whether you have
enabled bi-directional communications.
NOTE: This problem does not occur with the Generic/Text Only printer
To resolve this problem, use either of the following methods:
- Configure the port in your computer's CMOS settings to a non-PS/2
mode (for example, use standard LPT mode, or ECP or EPP mode).
NOTE: This option is not supported on all computers.
- There is an updated Lpt.vxd file on the Windows 95 CD-ROM that corrects
this problem. To install the updated file, follow these steps:
NOTE: If you do not have the CD-ROM version of Windows 95, you can
obtain the alternate Lpt.vxd file from Microsoft Windows 95 Service
Pack 1. For information about obtaining Microsoft Windows 95 Service
Pack 1, please see the following article in the Microsoft Knowledge
- Use Windows Explorer to rename the Lpt.vxd file in the
Windows\System folder to Lpt.old.
- Copy the Lpt.vxd file from the Drivers\Printer\LPT folder on the
Windows 95 CD-ROM to the Windows\System folder on the hard disk.
- Restart Windows 95.
Availability of Microsoft Windows 95 Service Pack 1
For additional information about the Lpt.vxd file, please see the
Readme.txt file in the Drivers\Printer\LPT folder on the Windows 95
The Lpt.vxd file from the Windows 95 CD-ROM is version 4.00.503. To check
the version number of your Lpt.vxd file in Windows Explorer, click the
file, click Properties on the File menu, and in the File Properties dialog
box click the Version tab.
Note that the symptoms described in this article can also be caused by a
printer switchbox. If you are using a printer switchbox, you may want to
disconnect the switchbox to see if the problem persists.
