The sheet enables trimming information such as the size and position of a trimming frame to be recorded thereon. The trimming information is once stored in a memory means. A control means controls a variable-magnification optical means on the basis of the trimming information read out from the memory means in such a manner that a printing and trimming operation is properly effected.
