Hewlett-Packard LaserJet II Softfont Problems with MathType 1.0 under Windows 3.1

The information in this document applies to:

MathType 1.0 (Win)

Windows 3.1

The problem

There is a known problem that can occur with downloadable softfonts when using a LaserJet II printer and Windows 3.1. Somehow the Windows 3.1 LaserJet II driver does not know about the softfonts for the printer. Since MathType installs softfonts onto your hard drive, this can lead to a potential problem when using MathType.


The following instructions are a workaround from Microsoft to get your LaserJet II printing MathType equations again.

  1. Open the Windows Control Panel.
  2. Open Printers.
  3. Select your LaserJet II printer and click Remove.
  4. Open up your Win.ini file. This is found in your Windows directory. You will do some editing of this file, so please be sure to make a backup before making any changes.
  5. Search for the LaserJet II header in your Win.ini file. It should look similar to this: [HPPCL,portname]
  6. Delete the lines (including this header) up to the next header.
  7. Close and save your Win.ini.
  8. Exit Windows 3.1 and switch to your Windows 3.1 directory. If you did not rename the directory during the installation, it will be named \WINDOWS. Once in your windows directory, move into your \SYSTEM directory.
  9. Delete the file HPPCL.DRV.
  10. Restart Windows 3.1.
  11. Open the Windows Control Panel.
  12. Open Printers.
  13. Add a new HP LaserJet Series II driver from the Windows 3.1 diskette.
  14. Now run MathType Setup and choose Custom Install.
  15. Select to only install Printer fonts.
  16. Select your LaserJet II printer and click OK.
  17. Restart Windows.
