摘要:
A control method and apparatus for a thermal head capable of printing two colors applies thermal history control using a simple circuit configuration. The thermal head control apparatus has a print data processing unit 40 and a drive control circuit 50. The print data processing unit 40 has a first command processing function for converting first color data to a first and second stage energizing commands, a second command processing function for converting second color data to a second stage energizing command, a first line buffer 43 for storing first stage energizing commands, and a second line buffer 44 for recording second stage energizing commands. The print data processing unit 40 selectively outputs energizing commands from the first line buffer 43 and energizing commands from the second line buffer 44. The drive control circuit 50 has a print buffer 52 and history buffer 53, and energizes the heating elements of the thermal head 10 based on energizing commands determined by a comparison of content stored to the print buffer 52 and history buffer 53.

A processing device is provided. A first storage unit stores a correspondence table which is indicative of a correspondence relationship between attributes of data and encryption levels for encrypting data. An obtaining unit obtains data. A first determination unit determines an encryption level according to an attribute of the data obtained by the obtaining unit, using the correspondence table stored in the first storage unit. An encryption unit encrypts the data obtained by the obtaining unit in the encryption level determined by the first determination unit. A second storage unit stores the data encrypted by the encryption unit.

A printing apparatus comprises a real-time command interpreter that functions even when the printing apparatus is off-line, and interprets control commands simultaneously with receiving data. The printing apparatus can therefore output pulses to the external devices even when printing is in progress or the printer is off-line. Such printing apparatus comprises a command detector for directly detecting predetermined command data from the received command data. An external controller controls an external device in accordance with predetermined command data detected by the command detection.

A host device requests a recording device to send first information including model information or sequel information expressed as a value in a first range. The host device determines if the model information or the sequel information is contained in the first information sent from the recording device, and acquires the model information from the first information if the model information is contained in the first information. If the sequel information is contained in the first information, the host device requests transmission of second information containing model information expressed as a value in the second range, and acquires model information from the second information. Based on the acquired recording device model information, the host device writes data stored in the host device to the recording device.

Without needing reserve printers of plural different types in preparation for an equipment failure, printing as desired can be quickly resumed by simply connecting a replacement printer. The printer 14 has two connection terminals enabling connecting to an external host computer 11 using a daisy chain connection, determines if an external device such as a host computer 11 or another printer 17 is connected to the connection terminals, and based on the result of said determination selects and prints from among specific plural types of print data output from the host computer through the daisy chain connection the print data of the type previously correlated to the connection status of the connection terminal.

A character reading system efficiently and quickly applies an optical verification process to detect magnetic ink character misreads. In the system, a magnetic ink character reading device reads magnetic ink characters on a processed medium and generates magnetic ink character data, an image reading device scans an image of the processed medium and generates image data, and a position calculator calculates positions of magnetic ink characters on the processed medium and generates magnetic ink character position information. A communication controller sends the magnetic ink character data, image data, and magnetic ink character position information to a host device which includes an optical recognition device that optically recognizes select magnetic ink characters from the image data based on the character position information. By selectively applying optical verification (e.g., only when character misread by the magnetic reading device is high), verification is required less frequently and high speed processing is enabled.

A printing apparatus for storing total operation counters for individual consumable and nonconsumable parts of a printing apparatus. A nonvolatile storage retains stored count information even when power is not supplied to the printing apparatus. An operations counter counts a value indicative of a printing apparatus operation. A counter storage stores a historical counter indicative of the printing apparatus operation history to the nonvolatile storage means based on a value counted by the operations counter, and stores a total printing apparatus operations count to the storage means. Specific printer operations, such as the number of characters printed, distance of recording medium transportation, and the number of times the automatic paper cutter is operated, can thus be individually accumulated, and the historical counts, that is, the cumulative counts since the printer was first used, can be stored to memory.
摘要:
In order to offer a printer capable of high throughput printing even when the same printing or printing that is partially different is repeated, the printing apparatus of present invention equipped with a storage unit for storing print image data based on print data received from the host device in a designated position and a printing controller and printer engine that performs print processing on the recording medium based on the print image data stored in the storage unit in accordance with control data received from the host device. Specifically, this printing apparatus features an erasure unit for selectively deleting print image data that has undergone the print processing from the storage unit in accordance with control data received from the host device. Also, the printing controller is preferably configured such that it performs the print processing in accordance with first and second types of control data, such that the erasure unit performs erasure processing in accordance with the first control data and does not perform erasure processing in accordance with the second control data.
摘要:
A printer and control method therefor for printing to a specific location on an inserted form whether the form is loaded automatically or manually in the printer. When a specific command is received from a host, the printer selects the insertion operation used for the printing form. If automatic loading is selected, the leading edge of the form is set to a specific position in the printer by a form transportation mechanism, and printing then begins. If manually positioned form insertion is selected, printing begins directly with the printing form as inserted and positioned by the user.
