    摘要: An information processing apparatus comprises: a memory to store emulation information which is designated from a host computer that is connected to a printer via a general parallel interface; a judging circuit to judge a delimiter of print data; and a control unit to switch the emulation on the basis of the emulation information stored in the memory and the result of the judgment by the judging circuit. When each section of the apparatus is in the inoperative state, they are set into the power saving mode and are sequentially controlled. Thus, the power saving of the whole apparatus can be realized.

    摘要: 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.
