To get your HP printer back online wirelessly, you should reconnect it to your Wi-Fi network using its control panel or touchscreen interface by running the Wireless Setup Wizard, selecting your Wi-Fi network, and entering the password. Alternatively, you can use the WPS button method if your router supports it for quick connection without a password. Make sure the printer is within range of the wireless signal and that your computer and printer are on the same Wi-Fi network[1].

Additionally, verify the following to ensure proper wireless operation:

– Check that the printer’s wireless light is solid, indicating an active Wi-Fi connection; if blinking or off, move the printer closer to the router or troubleshoot the Wi-Fi connection[4].

– Restart all devices involved—printer, router, and computer—to reset network states[2][3][4].

– On your computer, open “Devices and Printers,” right-click the HP printer, and make sure “Use Printer Offline” is unchecked and the printer is set as the default printer[2].

– If connection issues persist, reset the printer’s network settings via its control panel and reconnect to Wi-Fi[3].

– Consider reinstalling the HP Smart app or printer software on your computer to refresh the printer’s network configuration[3].

If your printer lacks a screen, you can connect it to your PC via USB to run the wireless setup through HP software, then disconnect USB when done[1].

Following these steps should restore your HP printer’s wireless online status.
