HP Printer on Mac, HP Envy Photo 7800 All-In- One  not printing or scanning, or copying.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, this seems like a hardware issue with the printer.  to provide an accurate resolution, I need a few more details:

• Did you make any changes to your printer? 
• When was the last time it worked fine?
• What are the troubleshooting steps you have tried so far?

While you respond to that, let's try these steps: 

• 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, and 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 the warm-up period finishes and the printer is idle. 

Hope this helps! Keep me posted for further assistance.
