I frequently print documents that are 30-80 pages, and they are always duplexed. This used to work flawlessly but after some updates (Win10 or HP drivers?) it is broken. Now the print job will stop after a few sheets, then auto-re-start and print the same sheets again and often one side more, then stop and start over. The printer is so good about sending "restart" messages to the spooler on the computer that I waste a ton of paper before I can get it stopped. I have run the HP test and fix programs, updated the drivers, etc. Nothing has helped.
