Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you.
I understand that you are facing issues while trying to do a 2-sided printing. To fix this issue, you need to install the printer drivers and then change the printing preference on the printer properties. Follow the steps below:
Let's try these steps here:
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” and “/s”)
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
13 ). Restart the PC
14 ). Now click on this link: http://ftp.hp.com/pub/softlib/software13/printers/OJ6970/OJ6970_Full_WebPack_40.11.1148.exe and install the updated printer software
15 ). Connect the USB cable only when prompted and follow the on-screen instructions to complete the setup.
Now, change the printing preference as suggested below:
Go to Control panel – Devices and printers.
Right-click on Envy 4522 and select “Printing preferences”.
Under the Paper/Quality tab, change the 2-sided printing option and make sure the option is turned on for 2-sided printing.
Now, come to the program that you are using to print and then change the setting to 2-sided in the application and then try printing.
