Printing system, printer, administrating device for the number of sheets, and program

A printing apparatus, comprising:

• a printing section configured to print based on a printing request received from a printing requesting apparatus, wherein the printing requesting apparatus is configured to transmit a printing permission request which includes information of a number of sheets of a first print job and does not include print data of the first print job, and wherein, the printing requesting apparatus is configured to transmit a printing request to the printing section after a printing permission for the printing permission request has been indicated,
• a first administrating section configured to calculate a number of printable remaining sheets until the number of sheets printed by the printing section reaches a predetermined upper limit of a number of printable sheets,
• a second administrating section configured to receive a number of reserved sheets of a second print job, the second print job provided with a printing permission and being under a waiting condition for being printed and outputted in the printing section, and
• a judging section configured to compare the number of reserved sheets and the number of sheets of the first print job included in the printing permission request with the number of printable remaining sheets calculated by the first administrating section, wherein the judging section is configured to determine whether the first print job requested by the printing permission request is to be permitted, and wherein the judging section is configured to transmit the determination as a response to the printing permission request.

An administrating apparatus, wherein the administrating apparatus is configured to communicate with a printing requesting apparatus and a printing apparatus, the printing requesting apparatus configured to transmit a printing permission request, wherein the printing permission request includes a number of sheets of a first print job and does not include print data of the first print job, and wherein the printing requesting apparatus is configured to transmit a printing request to the printing apparatus after a printing permission for the first printing permission request has been indicated, the administrating apparatus comprising:

• a first administrating section configured to calculate a number of printable remaining sheets until the number of sheets printed by the printing section reaches a predetermined upper limit of a number of printable sheets,
• a second administrating section configured to receive a number of reserved sheets of a second print job, the second print job provided with a printing permission and being under a waiting condition for being printed and outputted in the printing section, and
• a judging section configured to compare the number of reserved sheets and the number of sheets of the first print job included in the printing permission request with the number of printable remaining sheets calculated by the first administrating section, wherein the judging section is configured to determine whether the first print job requested by the printing permission request is to be permitted, and wherein the judging section is configured to transmit the determination as a response to the printing permission request.

An administrating apparatus for the number of sheets to be printed, wherein the administrating apparatus is connected to be able to communicate with a printing requesting apparatus to transmit a printing permission request including information of the number of sheets being scheduled to be printed to the administrating apparatus and transmits a printing request for the scheduled printing to a printing apparatus in the case of receiving a printing permission by a response from the administrating apparatus and a printing apparatus to print based on the printing request received from the printing requesting apparatus, the administrating apparatus comprising:

• a first administrating section for administrating the number of remaining sheets until the number of sheets printed by the printing section reaches to a predetermined upper limit of the number of sheets,
• a second administrating section for administrating the number of reserved sheets being under a waiting condition for being printed and outputted in the printing section, and
• a judging section for comparing the total number of sheets of the number of reserved sheets administrated by the second administrating section and the number of scheduled sheets indicated by the information of the number of sheets included in the printing permission request with the number of remaining sheets administrated by the first administrating section when receiving the printing permission request, for judging from the comparison whether or not the printing requested by the printing permission request is to be permitted, and for transmitting the judgment result as the response to the printing permission request,
• wherein, when the second administrating section receives a printing reservation registering request including information of the number of printing-scheduled sheets of a printing permission from the printing requesting apparatus having received a response of the printing permission from the administrating apparatus, the second administrating section adds the number of scheduled sheets indicated by the information of the number of sheets included in the printing reservation registering request to the number of reserved sheets, and
• when the second administrating section receives the information of the number of printed sheets printed and outputted based on the printing request from the printing apparatus, the second administrating section subtracts the number of printed sheets indicated by the information of the number of printed sheets from the number of reserved sheets, whereby the second administrating subsection renews the number of reserved sheets, and
• when the first administrating section receives the information of the number of printed sheets printed and outputted based on the printing request from the printing apparatus, the first administrating section subtracts the number of printed sheets indicated by the information of the number of printed sheets from the number of remaining sheets so that the first administrating section renews the number of remaining sheets.

A non-transitory computer-readable medium storing a program for administrating a number of sheets of a first print job to be printed, the program comprising:

• a first function configured to administrate a number of printable remaining sheets until the number of sheets printed by a printing section reaches a predetermined upper limit of a number of printable sheets, and wherein the first function is configured to administrate a number of reserved sheets being under a waiting condition for being printed and outputted in the printing section, the first function being configured to compare the number of reserved sheets and the number of sheets of the first print job with the number of printable remaining sheets when a printing permission request is received, wherein the printing permission request includes the number of sheets of the first print job and does not include print data of the first print job, and wherein the first function is configured to judge from the comparison whether the printing requested by the printing permission request is to be permitted, and to transmit the judgment result as a response to the printing permission request;
• a second function configured to transmit a printing reservation registering request including the number of sheets of the first print job to the first function after receiving a response of printing permission from the first function, and wherein the second function is configured to make the first function to renew the number of reserved sheets being under a waiting condition for being printed and outputted;
• and
• a third function configured to transmit a printing request for the first print job to the printing section, the printing request including the print data of the first print job.
