Overlay Function Set Commands
The overlay function 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 29 shows an overlay nesting.
