摘要:
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:
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.
摘要:
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 printing apparatus includes a data receiver that receives command data from a host device and a memory that stores the command data received by the data receiver. A printer controller reads out the command data stored in the memory in a first-in-first-out order and controls the printing apparatus in accordance with the command data. A command detector is provided to detect predetermined command data within the command data received by the data receiver without storing the command data in the memory or while or before command data is stored in the memory. An off-line recovery controller enables the printing apparatus to recover from an off-line state in accordance with the predetermined command data detected by the command detector.

A printing apparatus comprises a real-time command detector connected to the data receiver without the memory therebetween to detect control commands. Status data is transmitted to a host device in response to a real-time command from the host device.

This printing apparatus is provided having a regular status data generating circuit for regularly generating status data. An automatic status selection and transmission circuit selects the status condition to be transmitted by the automatic status transmission operation, and a status data comparator compares the status data. By executing the automatic status selection and transmission command, the status is thereafter transmitted each time the selected status changes.
摘要:
The printing apparatus of the invention provides a control command interpreter whereby control commands can be interpreted even in an off-line state. The cause of the off-line state can then be determined while in the off-line state, and the host computer can be notified of the cause. This achieves a high throughput rate printing. The user can cancel the cut-sheet paper insertion wait-state at any time, and determine why an error occurred to enable recovery from the error. This printing apparatus further provides high data reliability, reduces host computer overhead, and is easy to use.
