<P>PROBLEM TO BE SOLVED: To provide a disk processing system, capable of performing appropriate print processing with a simple structure. <P>SOLUTION: A control part confirms, prior to print processing, connection relations between two connection ports provided in the control part and two printers. Namely, the control part successively outputs a tray open signal to the upper connection port and the lower connection port, and temporarily stores drive detection results thereof at that time (S10 and S12). The control part determines normal connection when advance of a lower tray is not detected in step S10 and the advance of the lower tray is detected in step S12. The control part determines wrong connection when the advance of the lower tray is detected in step S10 and the advance of the lower tray is not detected in step S12. Further, the control part reports an error when a detection result other becomes than the above, and terminates processing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
