Abstract: In a digital scanner or other source for sending documents by electronic mail to a client, the size of the document is determined and a calculation is made of how many segments the document must be divided into. If the required number of segments is so large as to present a risk of flooding a network, a warning is displayed to a user. The system is particularly useful in the context of scanning to e-mail full-color images.

Abstract: An image forming apparatus in which an image is formed on paper without it being necessary for the user to identify and select paper having a suitable texture. Input image data is expanded to bit map data, and it is determined as to whether at least 30% of the expanded bit map data is a character image data region. When this determination is affirmative, a tray is selected, wherein paper having a glossiness such that its 45° reflectance is at most 20% is accommodated. If the determination is negative, that is, when at least 70% of the expanded bit map data is neither a character image data region nor a blank data region, a tray is selected, wherein paper having a glossiness such that its 45° reflectance is at least 50%, is accommodated. An image is then printed on the selected paper.
