@racer85,

Welcome to HP Forums,

If the wireless light is blinking and not connected. I would suggest here is to restore the printer to the network defaults. Once done, run the wireless setup wizard and connect the printer to the network.

To restore the printer to the network defaults: 

From the Home screen, touch (Wireless) and then touch ( Settings ).

Press an arrow button to move to Network, and then press OK.

Press an arrow button to move to Reset Wireless network, and then press OK.

Once done, Print the network configuration page to check if the network has been restored. 

From the Home screen, touch (Wireless) and then touch ( Settings ).
Touch Print Reports and then touch Network configuration Page.

Now run the Wireless setup wizard to the connect the printer to the network: 

1. From the printer control panel, touch ( Wireless ).
2. Touch ( Settings ).
3. Touch Wireless Setup Wizard.
4. Follow the display instructions to complete the setup.

If you're running Windows, I would suggest hre is to uninstall the printer from the root level and then reinstall it by following the steps below: 

• Press “Windows key” + “r” to get the “Run” window.
• Type "services.msc" to get Services – Go to “Print spooler” – Right-click and “Stop” the service.
• Now again open "Run" - Type “spool” and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, also try clean installing the printer drivers. Here are the steps:
• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP Officejet printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
• Please click here to download and install the software.
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.

Once the printer is connected using USB, please follow the steps to convert to Wireless connection : HP Printers - Changing from a USB to a Wireless Connection
