SYMPTOMS
When you print to the Hewlett-Packard (HP) DeskJet 500C from Windows 3.1, the following error message may appear:

Cannot find UNIDRV.DLL

CAUSE
When you install the HP DeskJet 500C printer, Windows 3.1 asks for an unlisted, updated, or vendor-provided printer driver.

If the Windows 3.1 Disk 6 (3.5-inch) or Disk 7 (5.25-inch) is inserted instead, Windows copies and expands the HP DeskJet family drivers (HPDSKJET.DR_ and UNIDRV.DL_) to the Windows\SYSTEM subdirectory but does not rename them to .DRV and .DLL, respectively.

RESOLUTION
If you receive this error, check the Windows\SYSTEM subdirectory for the files HPDSKJET.DR_ and UNIDRVR.DL_. If these files are present, rename HPDESKJET.DR_ and UNIDRV.DL_ to HPDESKJET.DRV and UNIDRV.DLL, respectively.

MORE INFORMATION
These drivers do not support color printing and may not interpret more than 16 colors when converting to gray scale while printing graphics.

We recommend that you obtain the correct printer driver for the DeskJet 500C (DJ500C.DRV) by calling the HP Fulfillment Center.
