HP OfficeJet Pro 8710

[CkHarnettTech]

I am having an issue when someone prints to our Office printer it will spit out a page of text at the top such as 

"% ! PS-ADOBE-3.0 %APL_DSC_Encoding: UTF8 %APLProducer: (Version 12.0.1 (Build 21A559" or "% ! PS-Adobe-3.0 Query userdict (\004) cvn {(\004 print flush} put %%?BegininFeatureQuery"

I assumed that had something to do with a driver? I checked to see and tried to update the drivers but it said they have the latest version. 

I also tried to reset back to factory settings and set the device back up and its still doing the same thing. 

The only thing I can think of is that, since it was set to automatically update the Firmware, that during maybe the power or internet connection went out. 

If theres a way I can revert to the old FIrmware and try to do another update let me know please, Ive spent a good hour or more on this and its a headache! 

Thanks

Hi @CkHarnettTech,

Welcome to the HP Support Community

I'd like to help!

To assist better-

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 

 Keep me posted.

Sorry for the delayed response.. 

Yes I have tried printing from Windows and Apple devices, both do the same thing. Ive tried printing from different applications such as google documents and word

Are you able to make copies using the printer?

Do the copies give you the same output?

Let me know!

Hey, No if I use it to scan and make copies it will print a copy just fine, no issues. Its only when printing from devices

Try the below suggestions -

1. Uninstall/update HP Smart 
2. Install HP Smart from the APP store 

1.    If installed from HP.com please delete from /Users/Username/Library/Application Support/HP Smart. Then delete HP Smart from the Applications folder and reinstall it from the Mac App Store.

2.   If downloaded from the Mac App Store please remove /Users/Username/Library/Containers/HP Smart/containers.plist and then launch HP Smart from the Applications folder and go through the setup again.

Try updating mac and printer firmware
 
To update the printer's firmware, refer - to HP Printers - Updating or Upgrading Printer Firmware 
 To update your Mac, try these steps - How to update the software on your Mac

Hope this helps!

Keep me posted!
