Abstract
A perfecting printer for performing a double-face printing operation of printing images on obverse and reverse faces of at least one sheet on the basis of a series of print data input from an external device and a method for controlling the double-face printing operation of the printer. The perfecting printer includes a page memory having an empty area for storing a series of print data for the obverse and reverse faces of the sheet input from external device, and a control unit for judging as to whether the empty area is no longer available in the page memory while the series of print data are being stored into the page memory and forcibly printing print data for the obverse face of the sheet on the sheet when it is judged that the empty area is no longer available in the page memory and that only the print data for the obverse face of the sheet are completely stored in the page memory.
