@Amoree1970, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to print from your phone. To assist you better, are you using the HP Smart app to print?

Do you see any options apart from this error?

Have you tried reinstalling the app? 

Try making a standalone copy from the flatbed glass and check if that works. By this, we can conclude if this is a hardware or a driver issue.

Sometimes resetting and clearing the Android OS Print Spooler cache can resolve the issue. On your Android device, tap the Settings icon, and select Apps or Applications. Select Show System Apps. Scroll down the list, and then select Print Spooler

Try printing.

Hope this helps! Let me know how it goes.
