7740 duplex printing not printing on long edge

[TonyHansen]

I just bought an HP OfficeJet Pro 7740, and it does not properly print duplex on the long edge. Regardless of whether I choose printing on both sides flipping on long edge or short edge, it always flips using the short edge. I've tried this with multiple applications, and it does this with each application I've tried. I've also tried this from multiple machines (both Windows 10 64-bit) and have had this issue. There are no error messages on either the printer or in Windows when this happens. Any help in resolving this would be appreciated.

@TonyHansen, Welcome to HP Support Community!

Follow the steps below to isolate and resolve the issue-

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printing/scanning issues. 

For more information, go to https://support.hp.com/us-en/topic/printscandoctor

Check the printer driver settings. Refer to the document for help- HP Printers - Print Driver Settings Guide (Windows)

If the issue persists, I recommend you delete the driver and root level and retry, follow the steps below: 

1) In Windows, search for and open Programs and features 

2) Select your HP Printer 

3) Select Uninstall 

4) In Windows, search for and open Devices and printers 

5) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 

6) Open up the run command with the “Windows key + R” key combo. 

7) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe”

8). Click on the “Drivers” tab 

9) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom 

10) Select Ok 

11) Select Apply and Ok on the Print Server Properties windows 

12) Close Devices and Printers.

Use this link to download and install the new driver. Configure the printer and try printing.

If you still have issues, try the Windows built-in drivers. Follow the steps below:

•   Uninstall the printer drivers. Go to Control Panel - Devices and Printers - Click on "Add printer" and follow the on-screen instructions.

•    When the page prompts for the drivers, select "Windows update". The driver list will be updated.

•    Click HP, Hewlett Packard, or Hewlett-Packard in the Manufacturer pane, and then click the name of your printer in the Printers pane.

Refer to this document HP Printers - Installing and Using the Windows Built-in Print Driver for help

Also, use the document How to Print on Both Sides of the Paper (Windows) (Duplexing) for detailed instructions on how to print two-sided.
