PRINTING DEVICE OF MFP USING MAIN CONTROLLER OF IDLE STATE, METHOD THEREOF, AND COMPUTER-READABLE RECORDING MEDIUM STORING COMPUTER PROGRAM CONTROLLING MFP

摘要

PURPOSE: A printing device of an MFP(Multi Function Product) using a main controller of an idle state, a method thereof, and a computer-readable recording medium storing a computer program controlling the MFP are provided to render print data by using the main controller of the idle state in a state that the print data is not rendered by a sub controller. CONSTITUTION: The sub controllers(30-34) generate a rendering request signal asking the main controller(36) to render the first print data and transfer it to the main controller in response to a result for checking that the sub controller already renders the second print data when rendering of the first print data is requested. The sub controllers transfer the first print data to the main controller by responding to the first control signal inputted from the main controller. The main controller checks the rendering of the first print data by responding to the rendering request signal, transfers the check result to the sub controller as the first control signal, and renders the first print data received from the sub controller.
