Re-Installing HP Deskjet 3755 After Change of WiFi

[Tsoshuwi]

I have had to replace my broadband modem and router, and my previous installation of my HP Deskjet 3755 no longer works. I have uninstalled the HP software and removed the printer from my device list, but, when I try to download and reinstall the software, I receive the message that the printer is already installed, and the process stops there. I tried reinstalling using a USB cable, but my printer is still listed as offline. It is running me in circles. What do I do to reinstall the WiFi connectivity using my new modem and router?

Hi @Tsoshuwi,

I'd like to help!

I understand you changed the router and would like to connect the printer to the new network.

Please try the steps below to connect your printer to the network.-

● Press the Wireless button ((i)) and the Cancel button (X) from the printer control panel at the same time, and then hold them for three seconds.

--->On the printer control panel, press the Wi-Fi Direct button.

---> When Wi-Fi Direct is turned on, the Wi-Fi Direct light is on steady. 

--->To find the Wi-Fi Direct name and password, press the Information button (i) for 3 secs to print a printer information page.

--->On your computer or phone go to wifi and connect it to your printer 

--->Select your printer with DIRECT in the name from the list of available networks (example: DIRECT-74-HP 3700)

Or 3600

--->Select the Wi-Fi Direct printer signal in Wi-Fi settings 

--->If prompted for a password, type 12345678. This is the default password.

--->Now open a browser and type 192.168.223.1

--->you will be able to access the printer's EWS page 

--->on the page, you will find network - click on it 

--->go to wireless and select wireless setup wizard

--->now select the network that you want your printer to connect to and type in the password 

--->the wireless blue light will stop blinking once the printer is connected 

--->then connect your phone back to your network
