Printer does not work after new router

[DennisL89]

A few days ago, I bought and installed a new router. After this, my printer does not work anymore. To be more precise: The wired connection does not work anymore. But if I try the wireless, it does.

The funny thing is, that regular print does not work with my wired connection. But if I enter the IP address in a browser, and print reports, it does work. So it seems, that my computer ARE connected somehow.

What could the problem be? I have swiched both my computer, printer and router on and off severalt imes, and the "HP Print and Scan Doctor" dosen't helt either.

It seems, that the router somehow "block" the printer, and I have to "whitelist" the printer someway. Am I right? And how can I do that?

By the way, the router is a "TP-Link Archer C7 Wireless Gigabit Wi-Fi Router - 1.75 Gbps"

Welcome to the HP Support Community.

Let's try to do a root uninstall and reinstall of the software:

Unplug any USB cable, if any, before doing this.

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.) Open up the run command with the "Windows key + R" key combo

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

15.) Restart the computer.

Once done, please download and install the software from here:

Hi Betty

Thanks for your answer. I didn't try your guide. But I did try to put the printer directly to our new router. And that works.

But when I put our printer back at our storage room, it won't work again. Could the number of routers the signal goes through be the problem? Is there a "limit"? I think it goes through 3 or 4 routers/swich now.

My colleagues, that are connected to another router in another, don't have any printer problems.

[Betty0610]

It could be. Did you try reaching out to your router company?

[DennisL89]

No, because the printer worked when I plugged it directly to the new router, together with my computer. So I assumed that the issue must be elsewhere. But I will try anyway. Maybe they know something about connecting their router to several others.

Sure, do keep us posted 🙂

I asked TP-Link support, and they helped with a solution. The problem was that my printer and my PC run on different IP-address. When I changed my new router to "Access Point mode", and after a reboot, the printer now works.

I'm glad to hear that. Do get back to us in the future for further assistance.
