When a printer driver is activated, a display controller displays, on a display device, default major categories for a variety of print processing functions that are linked to other, related major categories (functions). When a desired major category, such as "host interface", is selected, the display controller enlarges a display area, for "host interface", and displays, in the enlarged display area, mid-level elements located immediately below "host interface". When a desired mid-level element, such as "network" is selected, the display controller enlarges a display area for "network", displays in the enlarged display area all the low-level elements located immediately under "network", and also enlarges the display area for "host interface", which includes the enlarged display area. At the same time, the display controller reduces the sizes of the display areas for the other major categories, and displays them on the display device, so that they are not hidden under the enlarged display area.
