摘要： An information processing apparatus connected to a printing apparatus via a network encrypts print data if identification information is input, and does not encrypt print data if identification information is not input. If identification information is input and the print data has been encrypted, the information processing apparatus sends a print job including the encrypted print data to the printing apparatus via the network; otherwise, the information processing apparatus sends unencrypted print data to the printing apparatus via the network.

摘要： By smoothing a full-color image, staircasing of characters even in a gradation image is removed. An area to be smoothed is detected from image data having a plurality of color components, and image data included in the detected area is smoothed in units of color components. Image data which places an importance on resolution is smoothed by increasing the resolution to reproduce smooth characters and figures. Image data which places an importance on gradation characteristic is output without increasing the resolution, thus attaining high-gradation recording. A character or figure is detected from bitmap image data input from external equipment, and is smoothed. In correspondence with the density of the smoothed image data, the pulse width is switched, thereby changing the resolution of image data.
