Abstract
A printer driving method for fast release of control privilege provides a printer processor processing a render module and a filter module in the background. After processing the print command by an application program, a printer driver converts the print command of an output object into a particular meta file using a kind of printer language. Meanwhile, the meta file is submitted to the printer processor in the background and the control privilege is released to the application program at the same time. Thereby, the operation system has enhanced efficiency since the application program will not be suspended during the printing process.
