The CAPI hardcopy API is a mechanism for printing a Graphics Port (and hence a CAPI
output-pane
) to a printer. It is arranged in a hierarchy of concepts: printers, print jobs, pagination and outputting.
Printers correspond to the hardware accessible to the OS. Print jobs control connection to a printer and any printer-specific initialization. Pagination controls the number of pages and which output appears on which page. Outputting is the operation of drawing to a page. This is accomplished using the standard Graphics Ports drawing functions and is not discussed here.
