Hello again, I hope you enjoyed your weekend!:)
I am sorry to hear my suggestion didn't help. Next lets try a deep uninstall (Level 3 or 4, see details below) and reinstall.
Note: Do not run a Level 4 uninstall on a HP computer, this could cause damage to your operating system. A Level 3 is recommended for HP computers. A Level 4 uninstall is okay to be used on a non HP computer.
Uninstall:
1. Type %temp% in the run field and click OK.
2. Look for, and open the folder starting with 7z (Example: 7zS2356) (if there is more than one 7z folder, try the most recent one)
3. Open folder Util
4. Open folder CCC
5. Run the uninstall_ L4.bat for a non-HP PC or run the Uninstall_L3.bat for a HP PC
6. When the uninstall has completed restart the computer
Next, restart the computer
Then, reinstall the printer: HP Photosmart and Officejet Full Feature Software and Drivers: Windows 8
I am hoping that helps!
