Printer capable of refusing receipt of printed materials sent from an unintended source
A printer ( 100 ) for printing based on a print job signal sent from a data processing device ( 200 ) registers print job signal sending sources and a message corresponding to each sending source in memory ( 111, 112 ). A controller ( 113 ) detects whether the sending source of a received print job signal is registered in memory. If the sending source is registered, a messaging unit ( 110, 111 ) outputs a corresponding message. Sending sources that are permitted to print can also be registered in memory ( 111, 112 ). In this case, the controller ( 113 ) detects whether the sending source of a received print job signal is registered in memory, and instructs the printer ( 110 ) to print only when the sending source is registered as permitted to print.
1. A computer-readable data storage medium for storing a program for controlling a printing system, whereby printing according to a print job is accomplished when sending source information included in the print job to be executed coincides will a sending source preregistered as permitted to print to a corresponding output destination.
2. A computer-readable data storage medium for storing a program according to claim 1 for controlling a printing system, wherein said program deletes a print job if a print job sending source is not a sending source preregistered as permitted to print.
3. A computer-readable data storage medium for storing a program according to claim 1 for controlling a printing system, wherein said program notifies a user that a print job was received from an unauthorized sending source if a print job sending source is not a sending source preregistered as permitted to print, and deletes said print job in accordance with a deletion instruction from said user.
