Hi Dean, hope you are doing well.
Next time when you install any HP printer, consider installing/uninstalling it through REVO. Since you've already installed it REVO may or may not be able to remove each and every tiny traces but it still works --- www.revouninstaller.com ---
This is recommended for professionals, try it if you are comfortable with CMD.
Type 'CMD' (CMD window will open)
Type: net stop spooler --- hit enter ----
Type: net start spooler --- hit enter ----
Now Exit CMD
Next Goto: C:\Windows\system32\spool\drivers\w32x86
Now Delete everything inside "w32x86" folder
(remember, only delete stuff inside it and not the folder "w32x86" itself)
Restart the Computer, and have Fun
