 *
 * RETURNS:
 *
 *    If level is set to 1:
 *      Not implemented yet! 
 *      Returns TRUE with an empty list.
 *
 *    If level is set to 2:
 *		Possible flags: PRINTER_ENUM_CONNECTIONS, PRINTER_ENUM_LOCAL.
 *      Returns an array of PRINTER_INFO_2 data structures in the 
 *      lpbPrinters buffer. Note that according to MSDN also an 
 *      OpenPrinter should be performed on every remote printer.
 *
 *    If level is set to 4 (officially WinNT only):
 *		Possible flags: PRINTER_ENUM_CONNECTIONS, PRINTER_ENUM_LOCAL.
 *      Fast: Only the registry is queried to retrieve printer names,
 *      no connection to the driver is made.
 *      Returns an array of PRINTER_INFO_4 data structures in the 
 *      lpbPrinters buffer.
 *
 *    If level is set to 5 (officially WinNT4/Win9x only):
 *      Fast: Only the registry is queried to retrieve printer names,
 *      no connection to the driver is made.
 *      Returns an array of PRINTER_INFO_5 data structures in the 
 *      lpbPrinters buffer.
 *
 *    If level set to 3 or 6+:
 *	    returns zero (failure!)
 *      
 *    Returns nonzero (TRUE) on success, or zero on failure, use GetLastError
 *    for information.
 *
 * BUGS:
 *    - Only PRINTER_ENUM_LOCAL and PRINTER_ENUM_NAME are implemented.
 *    - Only levels 2, 4 and 5 are implemented at the moment.
 *    - 16-bit printer drivers are not enumerated.
 *    - Returned amount of bytes used/needed does not match the real Windoze 
 *      implementation (as in this implementation, all strings are part 
 *      of the buffer, whereas Win32 keeps them somewhere else)
 *    - At level 2, EnumPrinters should also call OpenPrinter for remote printers.
 *
 * NOTE:
 *    - In a regular Wine installation, no registry settings for printers
 *      exist, which makes this function return an empty list.
