SYMPTOMS
If you try to install HPPCL third-party scalable font support on a Hewlett-Packard (HP) LaserJet III printer (using the HPPCL5MS.DRV printer driver), you may receive a general protection (GP) fault in UNIDRV.DLL.

STATUS
Microsoft has confirmed this to be a problem in the PFM and PCM files generated by the PCL soft font installer (FINSTALL.DLL), which most third-party developers use to build the PCM/PFM files they distribute with their products. This problem does not occur if PFM/PCM files are built to the specifications described in the Windows 3.1 Device Driver Development Kit (DDK).

Microsoft has confirmed this to be a problem in FINSTALL.DLL. We are researching this problem and will post new information here as it becomes available.
