Abstract
A display and drawing control system, having a display and drawing control unit which produces screen data including characters and images and causes the screen data to be stored in a frame memory. The display and drawing control unit also operates on a display unit to display the screen data in the frame memory under control of a central processing unit. The system further includes an auxiliary memory in addition to the frame memory. The display and drawing control unit suspends the creation of screen data in the frame memory and stores other screen data in the auxiliary memory under control of the central processing unit. The system is further provided with a print data interface circuit which directly sends screen data from the auxiliary memory to a printer, thereby enhancing the operational efficiency of the system.
