Printing Duplex with HP LaserJet 5 PostScript Printer

MORE INFORMATION

To print duplex (print on both sides of the paper) on a Hewlett-Packard LaserJet 5/5M PostScript printer, the following conditions must be met:

1. The optional duplex unit must be installed and recognized by the printer. Print the self test page to verify that the duplex unit is correctly installed.
2. In the Windows NT 4.0 PostScript driver for the HP LaserJet 5/5M, make sure that the duplex option is enabled. On the Device Setting tab, click Duplex Unit in the Installable Options folder and make sure that the setting is Installed.
3. From the application software, select Print Setup on the File file and make sure that the Page Setup tab has the option "Print on both sides (duplex printing)" set to either "short edge" or "long edge" as preferred.
4. Set the resolution for the print job according to how much printer memory is installed. Additional memory is required to print duplex at 600 dpi or on larger paper sizes.

The following chart shows how much memory is required for specific paper sizes, resolutions and optional features when printing to the LaserJet 5/5M in Postscript mode. Note that less memory is required for PCL mode.
