vc将文件送入指定的打印机(根据打印机名)

如下：

 

BOOL PTKT_SendFiletoPrinter(LPCSTR pPrinterName, LPCSTR pFilePath){if(pPrinterName == NULL || pFilePath == NULL)return FALSE;DWORD tFileSize = 0;DWORD tReadFileSize = 0;char * tBuf = NULL;HANDLE tPrinter = NULL;// open the file and read data from the fileHANDLE tFile = CreateFile(pFilePath, GENERIC_READ, FILE_SHARE_READ, NULL,OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,NULL);if(tFile == INVALID_HANDLE_VALUE){return FALSE;}tFileSize = GetFileSize(tFile,NULL);if(tFileSize == 0xFFFFFFFF){CloseHandle(tFile);return FALSE;}tBuf = (char *) malloc(tFileSize);if(tBuf == NULL){CloseHandle(tFile);return FALSE;}memset(tBuf, 0x0, tFileSize);if(!ReadFile(tFile,(LPVOID)tBuf,tFileSize,&tReadFileSize,NULL)){CloseHandle(tFile);free(tBuf);return FALSE;}if(tFileSize != tReadFileSize){CloseHandle(tFile);free(tBuf);return FALSE;}CloseHandle(tFile);// open the printer and print dataif(!OpenPrinter((LPSTR)pPrinterName,&tPrinter,NULL)){free(tBuf);return FALSE;}if(tPrinter == NULL){free(tBuf);return FALSE;}DOC_INFO_1 tDocInfo1;memset(&tDocInfo1,0,sizeof(tDocInfo1));tDocInfo1.pDocName = "task1";tDocInfo1.pOutputFile = NULL;tDocInfo1.pDatatype = "RAW";if(!StartDocPrinter(tPrinter, 1,(LPBYTE)&tDocInfo1)){free(tBuf);CloseHandle(tPrinter);return FALSE;}StartPagePrinter(tPrinter);if(!WritePrinter(tPrinter,tBuf,tFileSize,&tReadFileSize)){free(tBuf);CloseHandle(tPrinter);return FALSE;}if(tFileSize != tReadFileSize){free(tBuf);CloseHandle(tPrinter);return FALSE;}free(tBuf);EndPagePrinter(tPrinter);if(!EndDocPrinter(tPrinter)){CloseHandle(tPrinter);return FALSE;}CloseHandle(tPrinter);return TRUE;}
