Hi RustyBC,
I suspect your question would be better answered in the HP Enterprise Business Community, as the LaserJet 1320 Printer series is a commercial model.
My technical expertise is with consumer products and software, I am sure the commercial folks would be happy to help if you re-post your question for them to answer. The HP Enterprise Business Community is an HP Forum designed for the Commercial and Enterprise customers to help one another. I am sure you will find some HP folks there to help too.
Click here to log into the commercial forum > HP Enterprise Business Community
You may find the HP LaserJet 1320 Printer series support page helpful while you wait for somebody in the commercial Forum to respond to your inquiry.
Best of luck.
