PSP.EXE 3.1 or Earlier May Causes Windows 3.1 to Fail

• Microsoft Windows operating system versions 3.1, 3.11

SYMPTOMS

When you run PSP.EXE version 3.1 or earlier under Microsoft Windows version 3.1, your system may stop responding (hang or lock up). MS-DOS programs lock up and you are unable to return to Windows. Windows or Windows applications may suddenly fail without an error message.

CAUSE

The problem is caused by another person on the network sending a print job to the non-dedicated print server running PSP.EXE. When the print job is captured by PSPrint, the user's machine hangs. The computer locks almost immediately when going to the MS-DOS command prompt or within a few commands after starting the MS-DOS session through Microsoft Windows when PSPrint is loaded before starting Windows.

WORKAROUND

To work around this problem, disable PSP.EXE before starting Microsoft Windows.

MORE INFORMATION

PSP.EXE is a terminate-and-stay-resident program (TSR) commonly loaded in the AUTOEXEC.BAT file or through a network batch file to support printing on a non-dedicated print server. PSPrint is a network non-dedicated printer driver that is run only on the computer that is physically attached to a shared printer. Users that send print jobs to the non-dedicated print server use the companion program QSLIM.EXE.

PSPrint is manufactured by Brightwork Development. They are aware of an incompatibility problem with Microsoft Windows version 3.1 and are working on correcting the problem.
