MORE INFORMATION

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.
