OJ Mobile Printer 250 AIO will not print. When you click "print" an error pops up on PC screen.

I had this printer for about 6 months or so. Want to use it mobily with Wi-Fi direct.  When I first got it had a heck of a time trying to get it to print. Got it working and manage to print about 20 pages. Stop printing became frustrated with it so I set it aside until now. Started it back up today and decided to use Wi-Fi network to connect and the same issue occurs.  I'm beginning to believe it's a "LEMON".  Connects to WI-FI fine but will not print. Throws up an error as soon as you press "Print".  I'm using Windows Surface Pro 6 connected to same Wi-Fi network as printer. Uninstall and Re-installed software 4 times no luck. Any suggestions? Thank you.

@RockAndChisel, Welcome to HP Support Community!

What is the exact error message on the PC screen?

Meanwhile, follow the steps below-

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues. 

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

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

Assign manual IP to the printer

The steps on how to set a manual IP address can be found here.

For the DNS servers please use 8.8.8.8 for the Manual Preferred DNS Server and 8.8.4.4 for the Alternate DNS server. These are Google’s public DNS servers

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 the 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.

Add a TCP/IP port.

1. Print a Network Configuration Report from the Printer Settings or Wireless menu.
2. Right-click your printer, select Printer Properties, click the Ports tab, and then click Add Port.
3. Select Standard TCP/IP Port, and then click New Port.
