Can't print half sheets on LaserJet M 501dn..

[JamesRB3]

I have a new HP LaserJet M501dn printer. It prints duplex on full sheets but I can get it to print half sheets. I've tried the A5 selection and custom page size of 5 1/2 inches by 8 1/2 inches. I want to print a 2 page document on one piece of paper. Flipping pages manually is tedious as the job is several hundred copies. I've tried all the various combinations of two sided printing I could find. BTW, I'm using WordPerfect X7 on a 64 bit Windows OS.. If I put the document on a full page, the printer prints duplex as expected.

Tired of flipping pages.

Not all page sizes are supported for automatic duplexing as the distance between feed rollers in the duplex path does not always support shorter paper.

Is your job a single page double sided? If so, just print all your first sides and then reload the tray and feed the paper for the second page. If they are different pages most drivers have a setting so you can print all the odd pages then flip paper over and print all the even sides

Thank you.

You'd think that after having six HP printers I'd have sense enough to check what functions were supported for each paper size.

I humbly accept the deserved dunce cap.
