Lost duplex printing after Mojave Installation

Hi - the following worked for me

1. https://www.imore.com/how-reset-printing-system-your-mac
2. https://discussions.apple.com/thread/5244577
3. When going into the print dialogue of Preview, you can check your settings in the "Printer Features" pull down
4. 

If it helps anyone else to see my settings - this is what I did.

File > Print

In the active window go to the 3rd pop up menu on the right "Layout"

Select "Printer Features" this opens a series of pop up menus - there are quite a through and you can scroll up and down.

Make sure

2-sided printing: ON

Binding edge: 2-sided long edge

Two-sided printing: Long-Edge binding

Duplex Tumble: DuplexNoTumble

Print document. If satisfied change your presets to Last Used Settings.

Are you using the "AirPrint" driver? That driver often doesn't have some of the features the full driver does.

If so, you can try Adding a printer, selecting yours, then select the full printer driver from the popup list.

Conversely, if you are using the full driver, try the AirPrint driver.

I have the same problem. Also, I'm able two print two-sided from Google Chrome, although the print menu comes up with "Save" instead of "Print", and I have to go to the "Print Using System Dialog" option that is presented.

I tried the fix recommended above, but I got a message saying "Unable to communicate with printer", even though my printer works when I try to print.

This worked for me - but only to the extend that the reverse page was upside down. Can I correct his?

That is usually controlled by the "binding edge" or something similar.

You want "long edge" or "flip over" instead of "short edge" or "flip up"

This worked for me - but only to the extend that the reverse page was upside down. Can I correct his?

This worked for me! Thank you so much - you're a genius.

Genius! Thank you very much! The DuplexNoTumble was actually the game changer for me. I did set all the other Printer Features options as you suggest but it doesn't work until you use this last one.

thank you that's very kind. It took reading the previous instructions and a Mojave handbook to work it out.

I dont see a Printer Features option at all. I am using an Epsom 960FWD. Please help as its difficult to manually print duplex and i dont like to waste one side.

this is what did the trick. Only now it allows only double sided printing as default.
