摘要:
Device and methods for acquiring by a host device model information (model ID) of a device assigned in a new range are provided herein. In many embodiments, the device includes a model information storage unit that stores model information from either a first range or a second range outside the first range and a communication unit that communicates with a device that requests model information, receives a model information request, and in response returns the model information if within the first range and returns specific information if the model information is outside the first range. After the specific information is sent, a new request is sent from the host device after which the communication unit provides the model information within the second range, often in a different format from the specific information.

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.

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.

An imaging device receives from a host image data and commands including a normal command and a real-time command to be processed prior to the normal command. A receiver receives a real-time processing disable command with a parameter indicating a number of bytes of the image data, and a processor processes the image data in terms of the number of bytes without processing the real-time command, after processing the real-time processing disable command. In a method for so controlling an imaging device, the host controls transmission of image data and commands including normal and real-time commands to an imaging device as noted above. The host comprises a detector that determines if data to be transmitted includes image data, and a processor that transmits the image data after transmitting a real-time processing disable command with the parameter described above, if the detector determines that the data includes the image data.

A power supply control apparatus for reducing the frequency of running a specific process in an electronic device when the device power turns on or off too soon after being turned off by monitoring the operating state of the power switch. When the power supply control apparatus detects an operation turning the power to the hybrid processing apparatus 1 off, the power supply control apparatus continues supplying power for as long as needed to complete a given shutdown process. However, if the power supply control apparatus 50 detects an operation turning the device power on again after the power supply stops but before reaching a predetermined reset voltage a reset and restart command is applied to the electronic device. More particularly, if an operation turning the power on again is detected during the period while the power supply is maintained to complete the shutdown process after the operation turning the power off is detected, the command restarts the electronic device without running a process normally run after start up such as a cleaning process in a printer.
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.
摘要:
In a printer 1, if a reset signal Vrst is supplied, an external reset signal V0 that can be recognized by software is supplied to a CPU 61. The CPU 61 stores the time when the signal V0 is recognized as a pause time into a nonvolatile RAM 62. Then, determination of whether or not the reset is intentional is performed based on a reset time interval which is sought from a plurality of the past reset times. If the reset is not intentional, an appropriate level of cleaning is instructed to an ink system 80; and if the reset is intentional, an initialization level of cleaning is instructed to the ink system 80.
