Update: Steps to resolve were inconclusive.


The issue appears to be exhibiting when printing using the Secure AirPrint feature for the HP printer in question.


I was able to solve the error report by using the native HP printer driver after installing the HP support files from Apple support downloads.


HP Printer Drivers v5.1 for OS X


Also removing and adding the printer again and selecting "Print Using" select the printer's driver and not Secure AirPrint.


Tested and working.
