HP 7855 no longer prints double sided, even though it has been selected

[utahmom9]

HP 7855 will not print double sided.  It will if I manually feed.  Pop up window has instructions to put paper in tray for second page.  This is a recent problem, is this a software update from HP or Windows?  I  do not want to do it manually as suggested.

Hi@utahmom9,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing double-side printing issues with the HP ENVY Printer.  

I have a few recommendations 

• Open the file to be printed, then open the printer Properties dialog box. Click the Printing Shortcuts tab, and then click Two-sided, duplex, printing. In the Print on both sides drop-down list, click Automatically. Select any other print settings wanted, and then click OK.
• Check for any pending Windows updates.
• Update the printer firmware
• Click here to download and install the latest printer firmware from your computer.
• Click here to know different methods of updating printer firmware.
• You may try reinstalling the HP Smart app and check if that helps.
• For more info, refer to - Print on both sides of the paper with an HP printer
