Abstract
In a printer control method, image-data processing which has previously been performed in a printer (printer unit) is performed by a host computer (host unit), so that the cost of the printer is reduced. More specifically, the printer unit includes a holding unit for holding control commands from the host unit, and an execution unit for executing the control commands. The host unit includes an analysis unit for analyzing printer commands, control-command forming unit for forming control commands from the printer commands, and a transmission unit for transmitting the control commands to the printer unit. The printer unit is controlled by converting printer commands into control commands in accordance with printing instructions provided from host-unit application software and transmitting the obtained control commands to the printer unit.
