Printer just went through a firmware update. After that duplex no longer worked. I removed, reinstalled latest driver. I went to settings, devices, printer & scanners, selected printer, manage, printer properties, device settings, selected duplex unit to installed. Still will not print duplex. Could the firmware block that on my printer?

Hello @foust61 ,
Welcome to the HP Support Community!
Only if a duplexer is installed:
Search Windows for 'devices', and then click the Devices and Printers control panel setting in the results.
Right-click the icon for your printer model, and then
click Device Settings tab
Installable Options > Duplexer: installed
If not, change to installed.
Hi@Valsimot ,
you are right, this printer does not have a duplexer.
Only manual duplexing is possible.
Hope this helps! Keep me posted.

The M452nw supports manual duplex only, can you confirm that you before firmware update used manual duplex ( not automatic).
Manual duplex is driver supported only there is nothing in the firmware that can turn OFF/ON manual duplex.
