ABSTRACT:
Methods of controlling an information processing device in the sending of commands to a printer for control thereof, methods of controlling transmission of bit-map data, and systems embodying data and command flow control distinguish between true and false real-time commands. In one aspect, it is determined if a data stream to be transmitted includes bit-map data. If so, then a real-time processing disable command is sent; and then the data stream including the bit-map data is sent. In another aspect, if the status of real-time command receipt is disabled, then a data stream including bit-map data is transmitted, followed by the transmission of a real-time processing enable command, and then the transmission of a real-time command. In a system including a host computer and a printer, a detector determines if a data stream to be transmitted from the host computer to the printer includes bit-map data, and a processor transmits a real-time processing disable command from the computer to the printer; and then transmits the data stream including the bit-map data to the printer, if and when the detector determines that the data stream includes bit-map data.
