1. A print control system comprising:
a print control device configured to establish an asynchronous duplex communication channel, and that generates print data, and outputs the generated print data through an established communication channel, the established communication channel being the as asynchronous duplex communication channel; and a printer that establishes the asynchronous duplex communication channel with the print control device, receives the print data through the established communication channel, and prints based on the received print data; wherein the print control device is configured to push print data to the printer without receiving a request from the printer; and wherein the printer initiates the establishing of the asynchronous duplex communication with the print control device by sending a message from the printer to the print control device.
