Hp deskjet 3755

[D_McD]

I cannot figure out how to connect to my printer and the hp app cannot find it.   Once upon a time it was connected. I haven't used it in over a year and now HP doesn't even recognize I had/have a printer. HP services cannot locate it and not in the list. I'm so frickin lost and just about to throw the thing out the window.

Hi @D_McD 

Welcome to the HP Support Community. 

I understand that you are facing connectivity issues. I’d like to help!

Make sure, your printer and your device are on the same network as 2.4GHZ only. 

Is it a private (Home network) or a public Wi-Fi connection? Wi-Fi direct? Or Hotspot?
What device are you using the printer with a Windows computer, Mac, Android, or iPhone?

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
