@dumb2,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I see from your post that you are getting validation error message while printing from your HP OfficeJet 8710 printer. Don't worry we'll work together to help you find a solution.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Do you get this error message on the printer screen or on the computer screen?

Did you try to run HP Print and Scan Doctor?

Are you able to make a copy from the printer?

What is the Operating system installed on the PC? Is it Windows or Mac

In the meantime, while you respond to this post with the details, let's try these steps here:

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

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 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.

If you are facing any issue while using the printer then try using HP Print and Scan Doctor (PSDR). PSDR is an automated tool which can diagnose and resolve printing and scanning problems. Please go to this link: HP Printers - Using HP Print and Scan Doctor (Windows)  to download and run HP PSDR. Once you open the program, select your printer and click on “Fix Printing” to automatically diagnose and fix the issue.

Let’s try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

If the coy comes out fine, then I would suggest this could be a software related issue. In this scenario, I would suggest here is to uninstall the printer from the root level and then reinstall them by following the below steps: 

• Press “Windows key” + “r” to get the “Run” window.
• Type "services.msc" to get Services – Go to “Print spooler” – Right-click and “Stop” the service.
• Now again open "Run" - Type “spool” and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, also try clean installing the printer drivers. Here are the steps:
• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP Officejet printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
• Please click here (Please select the correct Operating system and version of Windows before downloading and installing the full feature software for this printer).
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.
