I am no longer able to print double-sided on my Officejet 5740 from my Windows 10 PC. It used to work great. Then it started printing the back side page upside down no matter what "flip" setting I selected in the printer settings. Now when I select double-sided printing it just prints on separate sheets.
I tested the printer by printing from my Android phone and the double-sided print function worked fine.
I have gone to the HP site and downloaded & installed the latest full featured driver with no change.
I think the printer is still using a Windows 10 driver that must have installed during a Windows 10 update.
Any suggestions from anyone with the same problem that has solved it.
