An application program can overlap and print an overlay file and descriptor. The printed output is created using the form overlay function. Up to 2 gigabytes of data can be overlaid.
To use the form overlay function, complete the following steps before running the print program:
Create an overlay file.
Specify the overlay file name in the descriptor or the printer information file.
Specify the directory which contains the overlay file in the OVLPDIR parameter (overlay file storage directory name) in the printer information file.
If the overlay file name is specified in both the descriptor and the printer information file, the overlay file name specified for the descriptor is used.
If the overlay file directory is not specified in either the descriptor or the printer information file, the current directory is used as the overlay file storage directory.
