摘要:
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.

摘要:
A storage unit stores configuration information of a first network device connected to a network. An acquisition unit acquires information related to the operating status of the first network device. A detection unit detects if a second network device is connected to the network. A network configuration unit instructs/commands the second network device to configure itself using the configuration information of the first network device stored in the storage unit if the first network device is not operating when connection of the second network device to the network is detected.

When a communication port is occupied by a recording control unit, the communication port can be released as needed without causing an error or problem. A communication control unit 16 has a decision unit 44 that determines whether or not the USB port 18 can be released from the recording control unit 42 based on control commands input from the recording control unit 42 when the USB port 18 is occupied by the recording control unit 42 and an access request for the USB port 18 is received from another device, and a releasing unit 45 that releases the USB port 18 from the recording control unit 42 when the decision unit 44 determines that the USB port 18 can be released from the recording control unit 42.
摘要:
A method to update firmware in a plurality of peripheral devices and a computer using the method to reduce data transmission collisions and to reduce the time required to complete the update process. The process involves sending firmware update data from a computer that is connected to a communication network to printers or other peripheral devices that are also connected to the communication network. The computer 11 groups a plurality of peripheral devices (such as printers 13a1) connected to the communication network into separate transmission unit groups each containing up to a maximum number of peripheral devices with the maximum number determined by measuring the transmission speed of the network and thereafter deriving the maximum number by experimentation at the measured transmission speed. The update data for updating the firmware is transmitted to the peripheral devices of any one transmission unit group. Thereafter update data is sequentially transmitted to the peripheral devices in another transmission unit group but not until the completion of transmitting the update data to all of the peripheral devices in the first transmission unit group is confirmed.
摘要:
The time required to send firmware update data to a printer or other peripheral device is shortened without changing the communication speed. A server sequentially reads records of source data in a first format, deletes blocks of consecutive blank data that are contained in the object data in records of the first format and are longer than the management data in a second format, and segments the object data before and after the blanks, connects the object data in records of the first format into units of a certain length, generates management data for the segmented object data and generates management data for the connected object data to produce target records in the second format, and sends the update data composed of the target records of the second format to the printer. Records of the first format written in ASCII code are binary converted, and binary records in the second format are sent to the printer.
摘要:
In an information processing system, a host apparatus and a device are communicatively connected such that the host apparatus serves as a master and the device serves as a slave. The device is configured to establish a power-saving mode, when any command is not received from the host apparatus for a prescribed time period. A device driver is provided in the host apparatus. The device driver is configured to transit from a normal state to a suspended state when an operation command for operating the device is not received from an application running in the host apparatus for a prescribed time period, and to transmit a dummy response to the application, when an inquiry command is received from the application while the device driver is placed in the suspended state, without notifying the inquiry command to the device.
摘要:
A host device includes an application unit that outputs a first command or a second command, a receiving unit that receives the output first command or second command, a command control unit that converts the received first command to a third command, and converts the second command to a fourth command, and a host communication unit that transmits the converted third command or fourth command. A device includes a device reception unit that receives the third command or fourth command, a first operating unit that performs the first operation based on the third command, and a second operating unit that receives the fourth command and performs the second operation.
摘要:
Various kinds of value can be easily added to print data output from an existing application without modifying the existing application program. A value-adding method executes a process of adding value to print data output from an application on a computer that has one or more communication ports and executes a specific process by means of an application, and includes a data acquisition step of acquiring the print data at the operating system kernel layer before the print data is received at the communication port, and a data processing step that applies at the application layer a process of adding and/or deleting print content in the print data based on previously registered information, and outputs the data after processing to the specified communication port.
