<P>PROBLEM TO BE SOLVED: To provide a controller which can surely execute printing processing even if a time is required before a main control circuit is reset, and an image formation device and a printing system. <P>SOLUTION: Image data sent from a PC1 have an unnecessary data part not to be printed, and unnecessary data receiving processing and cancellation processing are carried out before a main CPU 6 is reset from a waiting state by a USB interface LSI11. After the main CPU 6 is reset, image data to be printed are sent to the main CPU 6. By making an unnecessary data cancellation processing time correspond to a time required for resetting the main CPU 6 from the waiting state to a printable state, the failure of the printing processing by a time-out is evaded, and the printing processing can surely be executed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
