Printing apparatus control, method therefor, and data processing apparatus using the printing apparatus

摘要

The invention relates to a printing apparatus in which a general command is converted to a real-time command depending on the needs, allowing fast status analysis and error recovery with fewer number of control commands without inconveniencing the user, a control method therefor, and a data processing using the printing apparatus. In the printing apparatus or the data processing apparatus including the same which is operated by transmission of command data and print data from a host computer, general data usually processed in order is converted to a real-time command using a real-time command identifier. The printing apparatus receives the data with the real-time command identifier and processes the command or print data designated by the real-time command identifier. The invention allows using a fewer number of commands to execute various controls.
