Abstract: [Problem] To provide a printer system, printer, and printer control method capable of quickly running a printing process after print data is received from a host device.

Abstract: When a communications terminal has stopped operating because it is off-line, data received from a host is efficiently stored to a receive buffer so that receive buffer full states cannot easily occur. A data interpreter interprets the receive buffer content in the input order. An action buffer stores interpreted commands. A command execution controller executes commands in the action buffer in first-in first-out order. The data interpreter continues interpreting the received data even when operation of the command execution controller is stopped, and kills without storing to the action buffer any real-time commands detected by the data interpreter.

Abstract: A print pattern recognition apparatus includes a storage unit which stores a plurality of signal waveform data, which is extracted according to a predetermined condition from standard read signal waveform data and which is associated with a plurality of corresponding standard MICR characters, a detector unit for reading the MICR characters printed on a recording medium to output read signal data, a comparator unit for comparing the read signal data output from the detector unit with the signal waveform data stored in the storage unit, and a recognition unit for recognizing the characters and symbols printed on the recording medium in accordance with a comparison result provided by the comparator unit.

Abstract: A printer for reporting a printer error state to a user using sound, a control method for the printer, and a data storage medium storing the control method as a computer-readable program use a printing unit (print head 208) that prints text or graphics, a detector (cover open sensor 251, no-paper sensor 252, temperature sensor 253) that detects specific printer error states, and settings memory (RAM 204) that stores a setting determining whether errors are reported using sound. A sound generator (buzzer 231) emits sound when a particular error state is detected by the detector and a setting instructing acoustic error state reports is stored in the settings memory (RAM 204).

Abstract: A status data transmission control apparatus and method reduces the buffer size needed for transmission and significantly reduces the communication load by storing the most recent status data (of continuously generated status data) and a history of status data changes in a dedicated buffer. The most recent status data and the history of changes leading up to the most recent status data are sent to the host.
