The interpreter control group analyzes the individual command to each emulation. The print group control is the
software module used in common by all emulations in CG control (bit map, scalable), image control, and bar
code pattern generation such as picture drawing. The base control group executes BIOS control for the host
interface, mechanism section, control panel, and memory.
