Update your printer driver with the latest version.

Another way to get this error message when you try to print from a third-party application is to use an outdated printer driver. Several concerned users who also had difficulty correcting the error message were able to solve the problem either by relying on the device manager to update the driver version or by manually updating it themselves.
