Hp 5255 won't print. Blue light flashing

Hi @Nancy1223 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

If the wireless light is blinking blue, it indicates that the printer has lost the wireless connectivity.

Let us try to restore the printer to the default network settings, and then use HP Smart to connect the printer to your Wi-Fi network.

Step 1: 

Restore network default settings on the printer, to do that - From the Wireless  or Setup  menu, select Network setup or Settings, and then select Restore Network Settings.

Step 2:

Uninstall and re-install the HP Smart app on your computer/mobile device.

Place the printer and the computer or mobile device near the Wi-Fi router.

Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.

Enable Bluetooth on the computer or mobile device so that HP Smart can detect the printer during the setup.

After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.

Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPadOS).

In HP Smart, click Add Printer or the plus sign to search for the printer, and then follow the instructions to complete the setup.

If this solution hit the spot, please come back and click "Accepted Solution" to help others find the answer. And if you'd like to say thanks, select "Yes" on the bottom left of the public post, as that would make our day! 

Take care, and have an amazing day!
