Officejet Pro 7740 will not print - Printer screen stuck with word "PRINTING" and spinning circle

[Denraceer]

We've been months without our printer and ended up buying a new Epson Photo Printer.

The Officejet Pro 7740 is 18 months old and will no longer print any print jobs. The printer will print test pages, alignment, and other setup pages with no problem.

When clicking print, the screen on my printer will show "Printing" with a circle spinning around the word printing. This will show on the screen for hours until I click cancel. <picture attached below>. 

1. This is the third time this has happened in 18 months and I am not sure what fixes the problem.
2. Test pages, printer alignment, network test pages all print perfectly fine, so I know the printer works and is on the network.
3. We are printing from a Macbook laptop, iMac desktop, Windows Surface Pro, and Windows 10 desktop. The same problem happens with all types of computers and "DIRECT" printing.
4. The problem occurs on Wi-Fi and hardwired ethernet.
5. Unplugged the printer and power cord numerous times. The printer is plugged directly into the wall and tried different outlets.
6. Factory reset the printer numerous times.
7. Connected the printer to a guest network, 2.4 GHz network, 5.0 GHz network, and hardwired to a switch.
8.  Added the printer with Secure Airprint, Airprint, HP Directjet.
9.  Autoselected drivers and also manually chose the HP 7740 drivers.
10. Firmware is up to date.
11. All cartridges are installed and have been reinstalled.

I am not looking for someone to congratulate me on my troubleshooting skills or ask me to perform any of the steps that I've performed above. I've searched for many days all over the internet and on the HP forums. No one has provided a solution to this problem other than recommending all of the steps that I've performed above.

@Denraceer, Welcome to HP Support Community!

Appreciate your time and efforts in trying to resolve the issue.

The only option left is to perform a full reset and re-initialize the printer. 

The reset instructions are specific for your printer and performing those steps on a different printer may brick the device. 

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
