摘要

PROBLEM TO BE SOLVED: To continuously efficiently print by judging on the basis of a designated predetermined printing condition whether or not printing by a plurality of sheets on a transfer drum is possible, judging whether or not continuous printing combined with a fraction page of a rear end of the print is possible, and determining a printing sequence. ;SOLUTION: An outer circumference of a transfer drum is in a direction of, for example, a long side of an A3 size, where two sheets are attached in the case of a small size up to an A4. When two sheets can be attached, i.e., in the case of the small size, an image-forming apparatus 201 judges in response to a two sheet attachment request whether or not two sheets can be attached and, sends back OK or NG to a controller 202. When the immediately previous printing is carried out to an odd number of sheets in total continuously under an equal condition in the two sheet attachment manner, the image-forming apparatus 201 judges whether an initial sheet sent at present is to be combined with the last sheet of the previous printing and gives the result to the controller 202 by either a two attachment continuance OK or a two attachment NG.;COPYRIGHT: (C)2000,JPO
