Deskjet 4645 no longer able to connect to computer via Wi-Fi

[rebeliyahu]

I've been using my HP Deskjet 4645 printer for a couple of years. It's always given problems communicating with my computer via Wi-Fi. Today, however, it completely stopped connecting. It used to get the print queue stuck and I had to remove the queue manually each time, restart the computer, restart the printer, restart the router. It took forever, but I had bought this printer so I had no choice now.

Today, however, I have gone through everything. I've restarted everything again, tried to reinstall the drivers etc. I just cannot get the computer to connect to my printer via Wi-Fi. It actually shows up as recognising that the printer is there, but upon trying to add it, it shows this screen with the green rectangle moving from one side to the other as it tries to search for being able to install the printer and then shows a screen saying "unsuccessful network connection." It doesn't help to retry connecting.

It is as if the working printer can only be thrown away now because it can no longer connect with the computer.

Is there any way to save this printer before doing anything drastic?!

Thanks.

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
