US Patent 7170614 Image forming apparatus

A printer is disclosed which automatically unifies the layout of output to each of mail bins. This printer sets the layout for each of the discharged paper trays (mail bins). The information of layout designated by a personal computer is invalidated when the layout has been set for the mail bins designated by an external personal computer. By storing in a memory the image data edited in the layout to be produced when the supply of papers has run out, the printer permits effective use of the memory and a reduction in the time of output.
