Hi @Newboy912,

Welcome to the HP Support Community

I understand you are facing an issue with your HP DeskJet 2721 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle

Update the printer firmware 

• Click here to download and install the latest printer firmware from your product

If the issue persists, then please uninstall the HP Smart app and also HP Print Service Plugin.

• Update your Android Device and Restart the phone once.
• Then try to print the photo. 

Hope this helps! Keep me posted.
