Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your HP ENVY Pro 6455 All-In-One Printer shows as online but fails to print with a “printer failed” message, try the following steps to resolve the issue:

1. Check Printer Status

• Make sure there are no error messages or warnings on the printer’s display screen.

2. Restart Devices

• Printer: Turn off the printer, unplug it from the power source, wait 30 seconds, then plug it back in and turn it on.
• Computer: Restart your computer to clear any potential software issues.

3. Check Printer Connections

• Ensure the printer is properly connected to your network if using wireless, or to the computer if using a wired connection.

4. Update Printer Drivers 

• Go to the HP Support website and download the latest drivers for your printer model. Install the updated drivers and try printing again.

5. Clear Print Queue

• Windows:
  1. Open the Control Panel.
  2. Go to Devices and Printers.

• Mac:
