/******************************************************************
* EnumPrintersA [WINSPOOL.174]
*
* Enumerates the available printers, print servers and print
* providers, depending on the specified flags, name and level.
*
* RETURNS:
*
* If level is set to 1:
* If level is set to 2:
* Not implemented yet!
* Returns TRUE with an empty list.
*
* 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 (faillure!)
*
* Returns nonzero (TRUE) on succes, or zero on faillure, use GetLastError
* for information.
*
* BUGS:
* - Only PRINTER_ENUM_LOCAL and PRINTER_ENUM_NAME are implemented.
* - Only level 4 and 5 are implemented at the moment.
* - 16-bit printer drivers are not enumerated.
* - returned bytes used/needed do not match the real Windoze implementation
*
* NOTE:
* - In a regular Wine installation, no registry settings for printers
* exist, which makes this function return an empty list.
