An HMD includes an image display section configured to display an image to be visually recognizable through an outside scene. The HMD includes a position detecting section configured to recognize an input and a control section configured to cause the image display section to display information and change the display in the image display section according to the input recognized by the position detecting section.

Display device, control method for display device, and computer program

An HMD includes a right light guide and a left light guide as a display section that displays an image with the display section mounted on a user's head in such a way that the user is allowed to visually recognize a real object. The HMD further includes a right sensor section and a left sensor section that detect approach of an instruction body to the right light guide and the left light guide and touchpads that accept operation. A control section of the HMD relates contents displayed in the right light guide and the left light guide to operation corresponding to motion of the instruction body detected by the right sensor section and the left sensor section in response to the motion of the instruction body.

A printing method is provided for printing on a medium with a color material by a printer including a cartridge accommodating section that removably accommodates a cartridge to which an advance payment information storage section for storing therein advance payment information is attached and which contains the color material. The printing method includes the steps of: reading/writing the advance payment information to/from the advance payment information storage section of the cartridge accommodated in the cartridge accommodating section; outputting a print driving signal for controlling to print; printing by using the color material in the cartridge based on the print driving signal outputted by the print controlling step; acquiring the print driving signal outputted by the print controlling step and converting the print driving signal to accounting information; and settling the advance payment information read by the advance payment information reading/writing step by the accounting information converted by the print driving signal converting step.

Printer including color material cartridge having removably attached advance payment information storage section

There is provided a printer that performs print on a medium by color materials, including: an advance information reading and writing section that reads and writes advance information from and in an advance information holder for storing the advance information; a print control section that outputs a print driving controlling print when the advance information is read by the advance information reading and writing section; and a used amount acquiring section that acquires a used amount for the printer based on the print driving signal output from print control section.

Facsimile systems, devices, and methods are provided related to transmitting an image from a sending device to a receiving device via a network. One embodiment includes a status information reply unit which replies to a notification request of status information from a sending device by transmitting status information representing status of the receiving-device to the sending device via a network, in which the status information reply unit includes a transmission source classifying portion which determines a class of the sending device and a selected-status information transmitting portion which transmits the status information to the sending device via the network.

A printer generates a public key with a passphrase containing at least printer position information and a random number by a public key cryptography, and holds this random number. A print client previously acquires the public key from the printer. When transmitting print data to the printer, the print client encrypts the print data in advance with the acquired public key and transmits the encrypted print data as print transmitting data. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information and the held random number by the public key cryptography. The printer then decrypts the received print transmitting data with the private key. Consequently, the security of the print data transmitted from the print client to the printer via a network is ensured.

Printer and print system, and data receiving device and data transmitting and receiving system

A printer generates a public key dependent on printer position information and transmits it to a print client. The print client encrypts a common key with this public key and transmits it to the printer, and encrypts print data with this common key and transmits it to the printer. The printer generates a private key dependent on printer position information to decrypt the encrypted common key, and decrypts the print data with the common key. Consequently, the printer capable of restricting the place where a print operation can be executed can be provided.

The network printerstores print logs generated after a previous log transmission timing into the log storage area, and then sends the print logs stored in the log storage areato the management serverat a next log transmission timing. The network printerstores a log relating to a print job into the log storage areaon completion of the whole print job when the next job transmission timing does not come before completion of the print job, while storing a log relating to a print job into the log storage areaon completion of every one page included in the print job when the next job transmission timing comes before completion of the print job. This arrangement desirably ensures transmission of logs relating to all jobs generated before each transmission timing to the management server.

In printing onto a creased paper with a fold portion, a printing method of the invention performs a warning step (S) that gives a warning about the need of smoothening out of the fold portion; and a printing step that starts printing after the warning is given in the warning step. The printing method further performs a reception step (S, S) that receives a confirmation instruction with respect to the warning given in the warning step, and the printing step does not start printing until the confirmation instruction is received in the reception step.

Printing method and printing program

A printer stores printer position information in sequence and calculates its representative value as statistical printer position information by a statistical method. When a public key is requested by a print client, the printer generates a public key with a passphrase containing the statistical printer position information and transmits the public key to the print client. The print client generates print transmitting data by encrypting print data with this public key and transmits the print transmitting data to the printer. The printer generates a private key with a passphrase containing the statistical printer position information at this point in time and decrypts the print data.

From a printer, a print client previously acquires printer position information on the printer. For example, when trying to transmit print data to the printer, the print client generates print transmitting data by adding printer position information on the printer to the print data and transmits the print transmitting data. The printer which has received this print transmitting data prints the print data only when the printer position information contained in the print transmitting data coincides with printer position information at this point in time. Consequently, the security of the print transmitting data transmitted from the print client to the printer via a network is ensured.

Printer server and print system and data receiving device and data sending/receiving system

A printer generates a public key with a passphrase containing at least printer position information, and holds the public key in a public key storage. When transmission of a public key is requested by a print client, the printer reads the public key from the public key storage and transmits the public key. The print clients transmits print transmitting data generated by encrypting print data with the previously acquired public key. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information. The printer decrypts the received print transmitting data with the private key.
