Abstract: Each agent unit gets status information indicating the state of each of network printers connected by a LAN from the network printers every first time period. Whenever each agent unit gets the status information from the network printer, it overwrites a status log data file with the gotten status information. Each agent unit converts all status information stored in the status log data file into status mail of electronic mail and transmits the status mail to a mail server every second time period longer than the first time period. On the other hand, a console unit accesses the mail server and reads the status mail in a proper time period to the console unit.

Abstract: The technique of the present invention enables quick completion of printing operations even when a large number of print jobs are concentrated on one printer. A print load distribution apparatus 80 monitors the job status in a buffer 55 and the error status of a printing mechanism 51 in a range of preset three computers 50, 60, and 70 among a plurality of computers connected to a computer network. When a number of print jobs are concentrated on one printer (for example, the printer 50) or when one printer (50) is in the error status, the print load distribution apparatus 80 takes in at least one print job stored in the spooling buffer 55 of the corresponding printer (50) and transfers the at least one print job to another printer (60 or 70) in the range of preset three computers 50, 60, and 70.

Abstract: The system of the present invention calculates a variation in balance between a commercial value and a price of an item before and after a predetermined revision and accumulates the calculated point in a Web server. When a customer who has purchased the item within a predetermined time period prior to a price revision or a functional revision of the item requires the Web server to output a customer's page allocated to the customer, the Web server displays the accumulated point in the customer's page. The Web server also displays specification of an available service corresponding to the accumulated point, for example, a discount on price of the item corresponding to the accumulated point. This arrangement of the system effectively wipes out the customer's feeling of loss due to the price revision or the functional revision of the item.
