Abstract: The invention is a method and system for establishing and printing a medium print field. The method begins with the initiation of a design software application which utilizes a display for representation of the medium and for displaying one or more component print fields on the medium representation. Each of the component print fields can be modified through utilization of a preferences input routine which further comprises: a printer selection option; a measurement scaling option; and, a return address selection option. The initiation further includes selection of a medium type and a set of characteristics for the medium. The representation displayed on the screen can be modified to the extent of its component print fields which comprise: a return address block; a postal indicia; a destination address block; and, a message block.
