摘要： In a printer controller which receives a command series containing a drawing command for instructing a drawing operation, and also a printing command for instructing a printing operation, the command series being transmitted from a host computer, there are employed a central processing unit and a memory unit, and a command buffer unit for storing the command series and a page buffer unit for storing plural pages of drawn dot image data are formed in the memory unit. The central process unit executes both a task process program for executing the drawing command and printing command as a drawing task and a printing task respectively, and a task control program for performing a task control for processing the respective tasks in this task process program. Further, a task control table for holding task control information is provided in the memory unit. The task control program performs a task control in accordance with a content of the task control table.
