All mandatory and simulated Presentation Manager functions are listed alphabetically in the following table. The two rightmost columns indicate whether a function is required for Hardcopy or Display drivers, or for both. A detailed description of each function follows the table. For ease of recognition, mandatory functions also include at the top of the page an icon of a printer, a display, or both, as appropriate.
