Abstract:

    Ansi end to winspool.drv

Author:

Environment:

    User Mode -Win32

Revision History:

    amaxa July 2000 - Modified GetPrinterData(Ex)A and SetPrinterData(Ex)A to
                      have the same behavior like the unicode functions.

/**************************** Function Header *******************************
 * DocumentPropertiesA
 *      The ANSI version of the DocumentProperties function.  Basically
 *      converts the input parameters to UNICODE versions and calls
 *      the DocumentPropertiesW function.
 *
 * CAVEATS:  PRESUMES THAT IF pDevModeOutput IS SUPPLIED,  IT HAS THE SIZE
 *      OF THE UNICODE VERSION.  THIS WILL USUALLY HAPPEN IF THE CALLER
 *      FIRST CALLS TO FIND THE SIZE REQUIRED>
 *
 * RETURNS:
