Abstract: An image forming device that forms an image on a print medium includes a power saving mode shifting part that shifts a mode of the image forming device to a power saving mode, in which power consumption is decreased, when a set power saving mode shifting time has elapsed during a standby mode, an idle time watching part that measures an idle time in the standby mode from a time of a completion of a previous printing to a time of starting a subsequent printing, a counting part that counts a number of times that the idle time has been equal to or longer than a preset idle reference time, wherein the number of times is a count value, and a shifting time setting part that sets the power saving mode shifting time in response to the count value.

Abstract: A printing apparatus includes a print drawing data storage storing first print drawing data from a print data generation apparatus, an administration information unit storing administration information of the first print drawing data, and an image processing unit. The print data generation apparatus includes a pattern data register registering pattern data corresponding to first image information, a pattern data converter, a first image converter converting the pattern data into the first print drawing data, a second image converter converting second image information into second print drawing data, and an image composition unit combining the first and second print drawing data. The image processing unit determines whether administration information of first print drawing data newly received and already stored in the administration information unit are the same. If so, the image processing unit combines the first print drawing data already stored and the second print drawing data.

Abstract: An image forming system is supplied which is able to prevent the record medium from being taken by other people and to improve the secrecy performance of image data.

Abstract: A printing system is provided that allows coordinates of pen strokes written or drawn with a digital pen to be correctly related to coordinates of application data even when the application data is printed in reduced size.
