刚写的一段代码，总是错误。哪不对了？
#include <windows.h>
#include <winspool.h>
#include <stdio.h>
int Print(char* szPrinterName, char* szBuffer)// szBuffer是我们希望发送到打印机的数据缓冲
{
HANDLE hPrinter; //打印机句柄
int iLen = strlen(szBuffer);// 发送数据的长度
DWORD dwWritten; // 已经向打印机写了多少
if(OpenPrinter(szPrinterName, &hPrinter, NULL))
//Open打印机并赋给一个句柄（已经保存在hPrinter)
{
DOC_INFO_1 Info;//文档信息
memset(&Info, 0, sizeof(Info));
Info.pDocName = "My PrintJob";
//文档名(which is shown in the PrintManager)
Info.pOutputFile = NULL;
//不须要向一个文件写，设为NULL
Info.pDatatype = "RAW";
//数据以RAW格式发送(Win9x和WinNT都支持RAW和EMF格式，WinNT还支持TEXT格式
if(!StartDocPrinter(hPrinter, 1, (LPBYTE)&Info))//文档开始
return 0;
// 告诉打印机开始新页
StartPagePrinter(hPrinter);
// 向打印机写数据
if(!WritePrinter(hPrinter, szBuffer, iLen, &dwWritten))
{
printf("print error!");
//当发送数据时出现错误
//用最后的错误指出发生了什么错误
}
EndPagePrinter(hPrinter);//告诉打印机已经完成当前页
if(!EndDocPrinter(hPrinter))//文档结束
{
printf("document have not end!");
return 0;
}
ClosePrinter(hPrinter);//关闭打印机
return 1;
}
else
