OverlayCommand Set
Overlay Com mand Set
The overlay command set contains the commands the printer uses to store,
delete, and present information in the overlay memory of the printer. These
commands are independent of any specific data types used in defining the
overlay.
The overlay is contained between the Begin Overlay (BO) command and the End
Page (EP) command and cannot contain itself. Overlays can be nested; that is,
overlays can contain other overlays. The depth of the overlay nesting cannot
exceed five levels.
Figure 25 shows an overlay nesting.
