LaserJet 4 PostScript Driver Does Not Have a 600 dpi Option (103357)

SUMMARY

The Hewlett-Packard (HP) LaserJet 4 PostScript printer driver (v2011.110) included with Windows NT does not have the 600 dots per inch (dpi) resolution as an option, although the printer is capable of printing 600 dpi in PostScript mode. To work around this limitation, install and use the LaserJet 4Si/4Si MX PS printer driver and use the Lower Tray as the default tray. This driver allows the printer to print 600 dpi, but the printer's tray selection will be different than the tray selection of the printing device because the LaserJet 4 doesn't have the same trays as the LaserJet 4Si/4Si MX PS. This could possibly cause problems in Windows-based applications such as Word for Windows, Excel for Windows, and WordPerfect for Windows, which allow for different tray selections. Make sure the Lower Tray is always selected.

Microsoft has confirmed this to be a problem in Windows NT version 3.1 and Windows NT Advanced Server version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
