Abstract:
PROBLEM TO BE SOLVED: To provide a printing method in which a print sheet can be reused. SOLUTION: In order to reuse a print sheet, a region of a print sheet printed with information is detected and a region related to that region is specified as an erasure region. Printed information is then erased from the erasure region by printing a pattern corresponding to the erasure region with erasing ink or toner of different color from that of printing ink or toner. Subsequently, print information is printed with printing ink or toner onto the print sheet from which the information is erased.

PROBLEM TO BE SOLVED: To effectively distribute advertisement information to each customer. SOLUTION: A customer registers personal information such as an address when the customer desires the distribution of information (e.g. cooking recipe, etc.), corresponding to the interest of each person. Even though advertisement information is attached to information to be distributed, the advertisement information is selected on the basis of personal data (e.g. discount coupons for specified items at a store in the neighborhood of the customer when an advertiser is a national chain supermarket). When a sales promotion item of the neighboring supermarket is, for instance, chicken, a recipe to be distributed is a cooking recipe in which chicken is used, is distributed preferentially so that the intention of the advertiser can also be reflected in a distribution content.
Abstract:
PROBLEM TO BE SOLVED: To realize reprint operation from a preferable page at the time of recovering from an error in a printer, e.g. incomplete sheet carriage, and resuming print operation. SOLUTION: The print system comprises a printer 10, and a jam recovery user interface section 30 connected with the printer and delivering a specified designation wherein the printer 10 comprises a data analyzing section 13 for developing print data 9 into a bit map image, a section 14 for storing the data developed into bit image based on the identification information of each page, and a section 20 for printing the bit map image onto a medium, and the jam recovery user interface section 30 comprises a section 32 for displaying the bit map image outputted from the printer 10, and a recovery object page designating section 33 for accepting a designation from a user and delivering the identification information corresponding to a designated page to the printer 10.
Abstract:
PROBLEM TO BE SOLVED: To secure an execution period for specific operation which is carried out when a processing request of a slave system is not executed by allowing a host system to send a pair of a preparation signal and an execution signal to the slave system at a certain interval and then allowing the slave system to judge the execution of the specific operation by calculating an estimated time needed to process the processing request by using the two signals. SOLUTION: When a data analysis and print data generation part 159 judges that data received from a job spool control part 157 are data other than data for printing such as command data, a time difference job signal detection part 161 inspects the data and instructs an independent timer measuring mechanism 171 to execute specific interruption when judging that the data are in a format corresponding to a time difference job signal. A specific function operation judgement and control part 163 inquires of a job process state monitor part 173, etc., to detect that a printer 150 is in specific conditions and instruct a specific function operation mechanism 165 to execute a specific function.
