Retrieves data for the specified printer.

If the function succeeds, the return value is TRUE; otherwise, it is FALSE. To get extended error information, use the GetLastError function.

hPrinter	Identifies the printer for which data is requested.
dwLevel	Specifies the version of the structure to which lpbPrinter points. This value must be 1, 2, or 3.
lpbPrinter	Points to an array of bytes that receives a PRINTER_INFO_1, PRINTER_INFO_2, or PRINTER_INFO_3 structure.
cbBuf	Specifies the size, in bytes, of the array to which lpbPrinter points.
lpdwNeeded	Points to a value that specifies the number of bytes copied if the function succeeds or the number of bytes required if cbBuf was too small.
