. On the printer's control panel, press and hold the Wireless button until the Wireless light starts blinking.

There could be several reasons why an HP DeskJet printer may not print. Some common reasons include:
1. No Power: Ensure the printer is turned on and properly connected to a power source.
2. Paper Jam: Check for any paper jams in the printer. Remove any stuck paper and make sure the paper tray is loaded correctly.
3. Empty or Low Ink: Check the ink levels in the printer. If the ink is empty or low, replace the ink cartridges.
4. Network Connection: If the printer is connected wirelessly, check the network connection. Ensure that the printer is connected to the same network as the device trying to print.
5. Driver Issues: Make sure the printer driver is properly installed on the computer. If not, download and install the latest driver from the HP website.
6. Print Queue Issues: Check the print queue on the computer. If there are any pending print jobs, try clearing the queue and restarting the printer.
7. Offline Status: Ensure that the printer is set to online mode. Sometimes, printers may go offline due to connectivity issues or other reasons. Go to the printer settings on the computer and set it to online mode.
If none of these solutions work, it is recommended to visit the HP support website or contact HP customer support for further assistance.
