SUMMARY
When you print to a Hewlett-Packard (HP) DeskJet series printer using the Windows version 3.1 printer driver HPDSKJET.DRV version 1.2 and the Universal Printer Driver UNIDRV.DLL version 3.1.2 or later, the printout may be incorrect or garbled. This problem does not occur when you use HPDSKJET.DRV version 1.2 with UNIDRV.DLL version 3.1.

This problem is corrected by using the updated printer driver, HPDSKJETC.DRV, version 3.1 or later. this driver can obtained by calling Hewlett Packard at (303) 353-7650.

MORE INFORMATION
HPDSKJET.DRV version 1.2 is programmed to use DRC (Delta Row Compression); however, the YMOVETO command that it uses does not clear the last graphics scan line, which is necessary for DRC. The YMOVETO command was corrected in HPDSKJET.DRV version 2.0.

UNIDRV.DLL version 3.1 does not support DRC so the problem does not surface because this part of the driver is unused. The new UNIDRV.DLL version 3.1.2 does support DRC.
