<P>PROBLEM TO BE SOLVED: To reduce a user's feeling of unfairness to the utilization frequency of interrupt printing to a printer regarding an interrupt printing system. <P>SOLUTION: The printer 3 holds possession points of each of information processors 1a-1n, and consumption points used for the reduction of the possession points, and delivers these points to the information processors 1a-1n of demand sources in response to the demand. The printer 3 has an interrupt print processing part 41 that allows the interrupt printing demand from the information processors 1a-1n to be cut in given top priority over any printing demand in queue management, and that reduces the possession points of the information processors 1a-1n by the consumption point portion while increasing the possession points of the information processors 1a-1n given top priority, by the consumption point portion. The information processors 1a-1n have interruption issuance processing parts 20 acquiring the possession points and consumption points from the printer 3 and issuing interrupt printing demands to the printer 3 when the possession points of the own processor are larger than the possession points of the processors 1a-1n for the transfer of highest priority and not less than the consumption points. <P>COPYRIGHT: (C)2007,JPO&INPIT |
