JSI Tip 0545 - How do I print Duplex with an HP LaserJet 5 PostScript Printer?

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

1. The optional duplex unit must be installed and recognized by the printer (use the self test).

2. On the Device Setting tab of the print driver, click Duplex Unit in the Installable Options folder and make sure that the setting is Installed.

3. In an application, select Print Setup on the File menu 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.

4. Set the resolution for the print job based upon how much printer memory is installed. Additional memory is required to print duplex at 600 dpi or on larger paper sizes. Here is a chart you can use: (less memory is required for PCL mode)
