Abstract: A printing system is provided which includes a printer, a job control section that supplies print job data to the printer, and a determination section that determines whether to execute printing of the print job data. In the printing system, the job control section generates determination information, which is information relating to printing the print job data, before the print job data are supplied to the printer. In the printing system, the determination section determines whether to execute printing of the print job data depending on the determination information and information relating to the status of the printer. In the printing system, the job control section supplies the print job data to the printer, when the determination result shows that the printing is possible.

Abstract: A printing device of the present invention has an additional function of switching over connection with two wireless networks. The printing device enters a user's wireless LAN based on first setting information, while establishing connection with a maker's wireless LAN based on second setting information to communicate with a printer, which is one of additional devices newly entering the user's wireless LAN. In response to a requirement from the printer, the printing device temporarily disconnects from the user's wireless LAN and enters the maker's wireless LAN to transmit setting information relating to the user's wireless LAN to the printer. This arrangement desirably relieves the labor of the user for settings in the additional devices to establish connection with the wireless network.

Abstract: A wireless network device, such as a printer, to enter an infrastructure-type user wireless LAN as a station, has an additional access point function. A printer having an ESS-ID ‘MM’ as an initial setting is connected with a user wireless LAN, which includes an access point and a personal computer and uses a common ESS-ID ‘XX’. In this case, the procedure changes the ESS-ID set in the personal computer to ‘MM’ to establish an infrastructure-type communication with the printer. This arrangement enables the ESS-ID set in the printer to be changed to the common ESS-ID ‘XX’ for the user wireless LAN without varying the ESS-ID set in the access point. The technique of the invention ensures easy connection of any device without sufficient input interfaces to the wireless LAN.

Abstract: 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.

Abstract: The network printer 30 stores print logs generated after a previous log transmission timing into the log storage area 32b, and then sends the print logs stored in the log storage area 32b to the management server 10 at a next log transmission timing. The network printer 30 stores a log relating to a print job into the log storage area 32b on 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 area 32b on 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.

Abstract: The invention enables to readily download device control software to control device. Once receiving a request from a client PC through a HTTP communication module 10, a printer PT identifies an OS used by the client PC from an environment variable attached to the request through an OS identification module 11. A driver location search module 11 searches a location address of a printer driver corresponding to the identified OS from a driver location database 12. A HTML generation module 14 generates a Web page in which a link to this location address is described and then informs the client PC of it as response via the HTTP communication module 10.

Abstract: 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.

Abstract: 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.

Abstract: A printer acquires a relative distance between the printer and another printer and holds the relative distance in an alternative printer list table. When selecting a printer to which a request for alternative printing is made, the printer searches relative distances in the alternative printer list table and selects a printer with the shortest relative distance as an alternative printer. Consequently, the printer to which the request for alternative printing is made or the like can be efficiently selected.

Abstract: A server computer acquires printer information containing printer position information from a printer and stores the printer information in a printer information table. When the printer information is request by a print client, the printer information is provided after authentication as required. The print client generates print transmitting data by adding the printer position information to print data and transmits the print transmitting data to the printer. The printer which has received the print transmitting data acquires printer position information at this point in time, and when the printer position information at this point in time coincides with the printer position information contained in the print transmitting data, the print data is printed by the printer.

Abstract: The technique of the present invention increases a variation in status used for management of print jobs, thereby enhancing utility of a printer. In a printing system constructed via a network LAN, a printer PRT includes a job management apparatus that manages statuses of print jobs in conformity with International Standard ISO/IEC10175-1. The job management apparatus has a create control module 6 in addition to diverse functional blocks for processing the print jobs based on the International Standard. When the user gives an instruction ‘create’ to a print job in a ‘held’ status, the create control module 6 creates a new daughter job from the print job in the ‘held’ status as a mother job and executes printing of either the mother job or the daughter job, while keeping at least one print job in the ‘held’ status. This arrangement enables a registered document to be reprinted iteratively at any arbitrary time.

Abstract: When a printer (30) prints a printing job of confidential printing which is a kind of printing of secret documents, even if the printer (30) itself is set to hold printing job data after printing, the printing job data are deleted without being held in a hard disk (32) after printing. Consequently, secrecy on the occasion of printing with some secret such as confidential printing can be heightened.

Abstract: The technique of the present invention facilitates execution of proof printing, prior to main printing. In a printing system constructed via a network LAN, a printer PRT includes a job management apparatus that manages statuses of print jobs in conformity with International Standard ISO/IEC10175-1. The job management apparatus has a proofComplete control module 6 in addition to diverse functional blocks for processing the print jobs based on the International Standard. The proofComplete control module 6 functions to hold a print job with attribute information representing proof printing after conclusion of proof printing. Separate management of the print job with the proof printing attribute enables a single print job to be utilized for both proof printing and main printing. This arrangement effectively enhances the utility.
