I am trying to set up double-sided printing to an Athena printer from a Windows machine, but the Printer properties will not retain the duplex settings.

Answer

Try the following:

1. First, be sure the bidirectional option is enabled under the Port settings. If this option is not enabled, the duplex unit option will not be retained.
2. If the problem persists:
   1. Uninstall the previous driver.
   2. Go to the HP download site and download the latest drivers available for the printer (HP8150) you are setting up.
      Note: You should close all applications and disable virus protection before downloading and installing the drivers. These two factors have been known to corrupt HP printer drivers during installation.
   3. After installation of the drivers, reboot your machine.
