HP InkJetPro 8710 Printer continues to go "off line" and requires frequent "rebooting"

[Disconnect77]

Prior to this time, the printer has been sustained in an "idle" mode and I could basically print at will.  I don't know if I accidently reset a time delay (etc.) To recover I've just "rebooted" the printer and printed the document I was working on.  Unfortunately, in what seems to be a short period of time, the printer goes off line.  What do I need to do sustain the printer in an idle mode?

Greetings @Disconnect77, 

Welcome to HP Forums and Thanks for the post. 

I understand that your printer keeps going offline. 

Not to worry, I will be glad to help. 

Are you able to make a copy on the printer?

Request you assign a static or manual IP address to the printer by following the procedure mentioned below and it will resolve the issue you are facing. 

• Obtain the IP address of the printer (which can found by pressing the “wireless” icon on the printer control panel)
• Enter the IP address on the web browser (Ex: chrome, IE) to enter the printer EWS page.
• Go to the “Network” tab, click on “Wireless (802.11) then click on “Network address (IPV4)
• Click on the radio button which says “Manual IP” and then click “Suggest a manual IP address” to give a manual IP address to your printer.
• Click on the radio button which says “Manual DNS server” and under manual preferred type 8.8.8.8 and under manual alternate type 8.8.4.4 (This is Google DNS server address)

Let me know if this helped.
