Abstract
A printing apparatus includes a measuring device for measuring the elapsed time for feeding a sheet of paper from its top edge to its bottom edge by feeding a first paper; a paper size calculating device for calculating a paper size on the basis of the measured time and the paper feeding rate which is determined by the printing apparatus; a calculated result transmitting device for transmitting the paper size calculated by the calculating device and informing an operator of the paper size; a comparing device for comparing the paper size calculated by the calculating device with the paper size specified by an external apparatus; a size setting device for setting within the printing apparatus the calculated paper size as a specified paper size for printing a second and later sheets when the above comparison indicates that both sizes match each other; a display device for displaying a mismatch of the paper size in order to inform an operator of the mismatch when the above comparison indicates that the paper sizes do not match each other; and a reprint control device for reprinting the page after the operator replaces the paper.
