I recently changed the connection from my printer to the computer from WiFi to USB. Now my printer is powering off after short periods of inactivity. No other modifications / changes were made that I am aware of. I've done everything I can think of to see if there is a "setting" for "power off", but I can't find one. Does anyone know what to do to fix this, and/or why it didn't do this when connected via WiFi?
(Though the header/title may be different, the steps will help resolve your concern).
If the issue persists, try the below steps:
Step 1: Change the energy settings (optional)
Your HP printer is designed to reduce power consumption when the printer is not active. Auto Power Off or Schedule On and Off enables the printer to turn off after two hours of inactivity. When you are ready to use your printer again, press the Power button to turn the printer back on.
Check the Schedule On and Off or Auto Power Off feature on the printer's control panel or through the software, depending on your printer model.
Step 2: Restart the printer
Restarting the printer might resolve any connectivity error states.
Step 3: Update the printer firmware
HP regularly releases printer updates. Updating the printer firmware might resolve the issue.
Step 4: Plug the printer directly into a power outlet
If the printer is plugged into a power strip or surge protector, the printer might not be getting enough power to properly function. To resolve the issue, plug the printer into a wall outlet.
