* Pass the correct handle to _RpcGetPrinter in GetPrinterW. * Pass an empty string instead of a NULL pointer as wszComputerName to the GetPrinterLevel* functions, because this variable is later used as source for StringCbCopyExW. * Don't check for GetLastError() == ERROR_SUCCESS in tests. Windows apparently only sets the last error in case of failure. The Printing code should probably be changed similarly in a future commit. Should fix CORE-14072
