  • Patent number: 8413174
    Abstract: A driver controlling device is disclosed. A UI module stores information of supportable functions of drivers in a function table, and obtains information of functions of a model of a new driver to be used described in model dependent data of the new driver. The UI module determines whether the obtained information of the functions of the new driver has been stored in the information of the supportable functions. When the obtained information of the functions of the new driver has not been stored in the information of the supportable functions, the UI module stores the information of the functions of the new driver which has not been stored in the information of the supportable functions in a un-supporting function list and prevents the new driver from using the information of the functions in the un-supporting function list.

  • Patent number: 8266543
    Abstract: A device driver or method that operate a periphery device. A display mode storage unit stores setting items, which are operable by a user using a user interface interfacing the device driver, into functionally mutually-related groups, as plates, the plates indicating display modes of the user interface for each group of the setting items. An alignment sequence setting unit sets an alignment sequence for the plates by allowing the user to set the alignment sequence. An arrangement unit arranges the plates in a plate display area on the user interface depending on the alignment sequence set by the alignment sequence setting. Each of the plates has a width that equals either a whole length or a half length of a width of the plate display area, and the arrangement unit arranges the plates in the plate display area depending on the alignment sequence set by the alignment sequence setting unit.

  • Patent number: 8135622
    Abstract: In a disclosed order support system, devices connected to a communication network are searched for and device information is acquired from each of the found devices. Specified information used for extracting devices to be monitor target candidates is obtained, which is specified according to a predetermined attribute in the device information. Based on the obtained information, devices to be monitor target candidates are extracted from among the found devices. A list of the extracted devices is displayed, and devices to be monitor targets are selected. Status information of a consumable element in each monitor target device is acquired and sent to an order-support apparatus. The order-support apparatus creates an e-mail including a URL of a website used for ordering the consumable element detected as being deficient according to the received status information, and sends the e-mail to an e-mail address associated with the device with the deficient consumable element.
