Is there someone else there that might have anothere suggestion?

I talked with a colleague to see what ideas we could come up with and at this point I suggest we do go ahead and uninstall and reinstall. 

The following may appear convoluted, but I've made it easy to follow and included everything you'll need to completely remove any remnants of HP software/driver:

Scrub/ Uninstall

• Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
• Click continue, click on one of the printers in the list.
• * Only do this step if you do not have any other HP Printers.  Hold down Control, Option and Command, While holding the three buttons down,
• Click uninstall.

Manually uninstall potentially remaining files - I apologize in advanced this is not a fun task! I will try to make it easy to follow. Some of the files described in the following steps may not be found, if you can't find one of the files or folders on your computer, don't be alarmed.

Move the files and/or folders to the trash, drag and drop

• Macintosh HD/Applications//Hewlett-Packard folder
• Macintosh HD/Library/Application Support/ - delete all files and folders regarding HP/Hewlett Packard
• In Macintosh HD/Library/Caches - delete all files and folders regarding HP/Hewlett Packard
• Macintosh HD/Library/Documentation/Help/ - delete all files and folders regarding HP/Hewlett Packard
• Macintosh HD/Library/Frameworks/HPServicesInterface.framework
• Macintosh HD/Library/Frameworks/HPSmartX.framework
• Macintosh HD/Library/Image Capture/TWAIN Data Sources/HP Scan Pro
• In Macintosh HD/Library/Image Capture/Scripts - delete all files and folders regarding HP/Hewlett Packard
• In Macintosh HD/Library/Preferences - delete all files and folders regarding HP/Hewlett Packard

Move Macintosh HD/Library/Preferences/loginwindow.plist to the desktop. NOTE: Not removing the file loginwindow.plist during the manual uninstall could cause the uninstall to be unsuccessful.

• In Macintosh HD/Library/Printer/hp - delete folder
• In Macintosh HD/Library/StartupItems, drag the following folders to the trash, HP IO and HP Trap Monitor
• In Macintosh HD/Users/USERNAME (this should have a symbol of a house next to it)/Library/Preferences, drag the following folders to the trash: *Any files beginning with com.apple.print, *Any files beginning with com.hp, *Any files beginning with Hewlett-Packard, *Any files beginning with HP or hp
• In MacintoshHD/Users/USERNAME/Library/Printers, drag any All-in-One printers listed here into the trash.
• Drag the HP icons from the Dock and drop it on an empty space on the desktop. The icon will disappear.

Close all open windows.
Restart.
Empty the Trash.
