Update firmware is stored as one binary file. The binary file includes firmware data necessary for operating a controller unit and root certificate data necessary for a printer apparatus to establish secure communication with a content server. Specific information in the root certificate data is extracted from the update firmware, and the extracted specific information is used to update a management table of the root certificate provided in a RAM. With this configuration, it is possible for an information processing apparatus to reliably acquire and update the root certificate data without greatly changing the original functional configuration.

In a printing system, a first apparatus transmits, to a printing apparatus, a printing instruction containing location information indicating the location of printing content on a network. When receiving the printing instruction, the printing apparatus updates the location information contained in the received printing instruction in accordance with a medium setting indicating a recording medium on which printing is to be performed, and issues a request for printing content corresponding to the updated location information through the network. In response to the request from the printing apparatus, a second apparatus transmits the printing content corresponding to the updated location information to the printing apparatus through the network, and the printing apparatus receives the printing content and performs printing of the printing content on the recording medium. Accordingly, printing content suitable for a printable region of a medium on which printing is to be performed can be easily acquired and printed.

When a plurality of information signal processing apparatuses are connected via IEEE 1394 communication control buses, these buses are connected via bridges, and bus reset occurs on a remote bus other than connected buses (step S1501), occurrence of remote bus reset is notified (steps S1502, S1505). Thus, even if bus reset occurs, the consistency of bus reset processing in an upper protocol layer can be ensured to realize normal data communication between buses.

A host device logs in a printer as a print data transfer destination to acquire type information of the printer and issues SB_CONT.req to determine whether a cycle master necessary for isochronous transfer is present on a serial bus. The print data transfer mode and transfer parameter are set in accordance with the presence/absence of the cycle master and the acquired type information. If the cycle master is present on the serial bus, isochronous transfer is set as the transfer mode; otherwise, asynchronous transfer is set as the transfer mode. Therefore, even when devices without any cycle master function are connected, or no cycle master is present on the bus, print data can be transferred from the host device to the printer.

A document processing apparatus includes a first determining unit including a CPU for verifying the spelling of a word while referring to the first correct spelling information stored in a first spelling dictionary; a second determining unit including its own CPU for verifying the spelling of a word different from those stored in the first spelling dictionary while referring to the second correct spelling information stored in a second spelling dictionary; a connection unit for detachably connecting the second determining unit to the apparatus main body; and a switch for switching the spelling verification determining process between the first and second determining units in accordance with the connection state of the second determining unit relative to the connection unit.
摘要:
It is determined to cause the printing apparatus to print when the printing apparatus receives a first print job which is issued and does not cause the printing apparatus to print. When it is determined to cause the printing apparatus to print, the print control apparatus controls the printing apparatus to print an image corresponding to a second print job for causing the printing apparatus to print based on the second print job.

A printing apparatus is caused to print an image in which elements included in a document are arranged on a page by a print control method. The document, which includes the elements and information for arranging the elements, is acquired. An element disposed on an edge of the page is detected from among the elements included in the acquired document. The printing apparatus is caused to print an image in which the elements included in the document are arranged on the page and in which the element disposed on the edge of the page is expanded to a predetermined output area.
摘要:
A data transmission system where an image providing device and a printer are directly connected by a 1394 serial bus, a command is sent from the image providing device to the printer, then a response to the command is returned from the printer to the image providing device. Image data is sent from the image providing device to the printer based on information included in the response. The printer converts the image data outputted from the image providing device into print data. Thus, printing can be performed without a host computer by directly connecting the image providing device and the printer by the 1394 serial bus or the like.
摘要:
In a system where a digital still camera 1101 is connected to a printer 1102 on a 1394 serial bus, when the digital still camera 1101 as a data transfer originator node transfers image data to the printer 1102 as a data transfer destination node, the printer 1102 sends information on the data processing capability of the printer 1102 to the digital still camera 1101 prior to data transfer. The digital still camera 1101 determines the block size of image data to be transferred in accordance with the data processing capability of the printer 1102, and sends image data of the block size to the printer 1102. The information indicates the capacity of a memory of the printer for storing print data, or the printing capability of a printer engine, i.e., printing resolution, printing speed and the like. Thus, data transfer is always efficiently performed regardless of the data processing capability of the printer 1102.
