Media processing device, control method for a media processing device, and recording medium storing a program executed by a control unit that controls a media processing device

摘要

Media processing devices, media processing device control methods, and computer-readable recording mediums storing programs that can be executed by control units that control media processing devices are provided. In one embodiment, a media processing device has a plurality of operation units that process roll paper and checks as a plurality of recording media, and a central processing unit (CPU) that controls the operation units by executing commands received from a host computer. When the CPU detects during a normal operating mode that commands for any of the operation units cannot be executed, the CPU switches to a limited operation mode in which commands for that operation unit cannot be executed, but commands from the host computer can be received and commands for other operation units can be executed.

主权项

1. A media processing device comprising:
a roll paper operation unit that processes roll paper and that has a roll paper recording unit for recording on the roll paper; a slip operation unit that processes slips and that has a slip recording unit for recording on the slips; and a control unit that executes commands received from a host computer and controls the operation units, when the control unit detects in a normal operating mode that commands for the roll paper operation unit cannot be executed, the control unit switches to a limited operation mode wherein commands for the roll paper operation unit cannot be executed such that the roll paper recording unit cannot record on the roll paper and commands from the host computer can be received and commands for the slip operation unit can be executed, without switching the control unit to the normal operation mode, such that the slip recording unit can record on the slips, and when the control unit detects in the normal operating mode that commands for the slip operation unit cannot be executed, the control unit switches to the limited operation mode wherein commands for the slip operation unit cannot be executed such that the slip recording unit cannot record on the slips and commands from the host computer can be received and commands for the roll paper unit can be executed, without switching the control unit to the normal operation mode, such that the roll paper recording unit can record on the roll paper; wherein the control unit sends a signal to the host computer indicating that commands for the one of the operation units that cannot execute commands cannot be executed when entering the limited operation mode.
