FIELD: physics, computer engineering.SUBSTANCE: medium control device includes a plurality of operating modules which process rolled paper and receipts as a plurality of recording media, and a CPU which controls multiple operating modules by executing commands received from a host computer. When the CPU detects during a normal operating mode that commands for any of the operating modules cannot be executed, the CPU switches to a limited mode, in which commands for that operating module cannot be executed, but commands from the host computer can be received and commands for other operating modules can be executed.EFFECT: avoiding interruption of all functions of the device when recording is prohibited in the device, having multiple functions, including recording on a recording medium.13 cl, 8 dwg |
