<P>PROBLEM TO BE SOLVED: To easily grasp that the operating state of a printer is in an inappropriate state. <P>SOLUTION: In verifying the operating status of a printer 40 capable of counting the number of times of printing operations by a credit counter 44, a print server 20 determines the ratio of the total sheet number of prints included in a print command outputted from the print server 20 to the printer 40 within a predetermined time to the number of times of printing operations sent from the printer 40 within the predetermined time. When the ratio is within an allowable range, the print server 20 decides that the operating status of the printer 40 is appropriate, and when the ratio exceeds the allowable range, the print server 20 decides that the operating status of the printer 40 is inappropriate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
