My Hp printer officejet 6600 is locked up.
It is a Efficiency and high performance printing is essential in the production of high quality prints, but at such issues any device may have such problems. To resolve such issues try to un-install the drivers and re-install the printer drivers.
As the hp lock setting will be remove from the system files and re-installation will add up some new features and ehnace the printer proformances too.
