Dynamic link libraries for presentation drivers must export the appropriate set of the following entry points:

  EXPORTS
     MoveCursorBlock    @103           /* Display drivers only  */
     OS2_PM_DRV_QUERYSCREENRESOLUTIONS /* Optional              */
     OS2_PM_DRV_DEVMODE                /* Hardcopy drivers only */
     OS2_PM_DRV_DEVICENAMES            /* Hardcopy drivers only */
     DrvInstall                        /* Optional              */
     DrvRemove                         /* Optional              */
     OS2_PM_DRV_RING_LEVELS            /* All drivers           */
     OS2_PM_DRV_ENABLE_LEVELS          /* All drivers           */
     OS2_PM_DRV_ENABLE                 /* All drivers           */

In addition to the entry points listed above, hardcopy drivers should export entry points for the routines that handle dialogs with the user. See Exported Entry Points (Cursor); also see Exported Entry Points and Exported Driver Function Reference.
