I don't know much about printer software...but it can become corrupted/damaged just like any other file. When that happens, the file cannot function properly and may present problems.
Printer software, in such cases, can be removed totally...then reinstalled, if desired.
To remove it, all software installed via the HP printer disk...must be uninstalled. If this cannot be done via Add/Remove Programs, I normally try a tool such as Revo Uninstaller. Another alternative to attempt to uninstall from safe mode.

When I have printer problems...I also temporarily disconnect the printer via the USB cable. When I reinstall it, I reconnect, following the instructions provided by the printer manufacturer for doing so.
