Why does OfficeJet Pro 8720 keep going offline?

[RoyMI]

Printer goes offline several time daily.  I have to turn printer power off and back on to correct.  Printer is online after I do this.

There are a bunch or reasons the printer may not stay connected to your network.

Easy ones first: 

The printer may simply need a Firmware Update.  

If you have not done so, consider updating the Firmware

Always read any / all provided information before updating the firmware.

The Doctor might be able to find and fix the issue for you.

The Doctor:  HP Print and Scan Doctor for Windows

Dig at the problem and determine the fix.

Documents can help you navigate what is wrong and help you decide what to do about the issue(s) you have - what works depends on the type of connection.  For example, read about "Wired" connection setup if your printer is connected to your network via Ethernet.  If you are depending on Wireless, read the appropriate help for that type of connection,
