Abstract

An image scanning and printing device includes a printing unit that prints an image onto each of multiple sheets of recording papers in one printing process by a multi-up printing process and a control unit that controls to select and execute the multi-up printing process when a size of the recording paper, which is obtained based on a size of an original document and an output magnification, is less than half of a maximum recording paper size, and a number of sheets to be printed, which is obtained based on a number of original documents and a number of sets of sheets to be printed, is two sheets or more, and to select and execute a one-up printing process otherwise.

Description

field of invention [0001] The present invention relates to an image scanning and printing apparatus, and more particularly to an image scanning and printing apparatus that prints images on two or more recording sheets in one printing process. Background technique [0002] A conventional electrophotographic type image scanning and printing apparatus that prints a color image by a four-pass method uses four color toners of black (B), cyan (C), magenta (M), and yellow (Y). One cycle starting with image development based on the color data of each color and ending with transferring the image onto a medium is performed for each color data of each color. Then, the formed color images are collectively transferred onto the recording paper by overlaying the images one by one on the transfer medium. In the color image printing process using the four-pass method, for each of the four colors KCMY, an image is formed on a transfer medium, and thereafter, the color image is printed on rec...
