Abstract: A network printer to control a print queue and a controlling method thereof. The network printer to control a print queue includes a communication interface, a print job manager and a print engine. The communication interface receives print job information for print scheduling from at least one host computer. The print job manager determines a print queue of the received print job information based on a predetermined reference scheduling rule, and requests the at least one host computer to transfer print data. The print engine prints the print data received from the host computer. The print queue is determined through two steps, thereby effectively performing the print.
