The information in this article applies to:

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0, on platform(s):
   - the operating system: Microsoft Windows 95 
-------------------------------------------------------------------------------

SYMPTOMS
========

After loading the HP LaserJet 4000 TN PCL 5e driver as either the default
printer driver in Windows 95 or as the default printer driver in Visual FoxPro,
the following error may occur when you try printing several large reports:

  This program performed an illegal operation and will be shutdown.

When you press the Details button, the following message appears:

  VFP caused a general protection fault in module KRNL386.EXE at 0001:000014f1.

This error does not seem to occur when you run Visual FoxPro on Windows NT 4.0
using the Windows NT version of the HP LaserJet 4000 TN PCL 5e driver.


STATUS
======

Microsoft is researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Behavior
---------------------------

1. Install the Windows 95 HP LaserJet 4000 TN PCL 5e printer driver on a
  computer that is running Windows 95.


2. Set the LaserJet 4000 TN PCL 5e as the default printer for Windows. The
  driver can be directed to a file if you do not have an HP LaserJet 4000
  printer.

3. Create a quick report called Ztest using the Orditems table located in the
  \Sample\Data folder. The report should use the LaserJet 4000 TN PCL 5e driver
  as the default.

4. Place the following code in a program and run the program. The code prints
  the Ztest report to a text file 1000 times.

        USE Home()+"\Samples\Data\Orditems.dbf"
        FOR i= 1 to 1000
        REPORT FORM ZTEST NOCONSOLE TO FILE Ztest.txt
        DELETE FILE Ztest.txt
        ENDFOR

Depending on the speed of the computer, this error may take quite some time to
appear.
