C# 如何设置打印机 字体

[qinfei]

想通过普通打印机，将条码打印出来。
目前有39码的字库，已经安装到系统去了。
在WORD文档中写了几个字，将字体设置为条码字体，已经打印成功。

如何在C#中设置字体打印？

public class PrintDirect
{
[ DllImport( "winspool.drv",CharSet=CharSet.Unicode,ExactSpelling=false,
CallingConvention=CallingConvention.StdCall )]
public static extern long OpenPrinter(string pPrinterName,ref IntPtr phPrinter,
int pDefault);
[ DllImport( "winspool.drv",CharSet=CharSet.Unicode,ExactSpelling=false,
CallingConvention=CallingConvention.StdCall )]
public static extern long StartDocPrinter(IntPtr hPrinter, int Level,
ref DOCINFO pDocInfo);

[ DllImport("winspool.drv",CharSet=CharSet.Unicode,ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern long StartPagePrinter(IntPtr hPrinter);
[ DllImport( "winspool.drv",CharSet=CharSet.Ansi,ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern long WritePrinter(IntPtr hPrinter,string data,
int buf,ref int pcWritten);

[ DllImport( "winspool.drv" ,CharSet=CharSet.Unicode,ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern long EndPagePrinter(IntPtr hPrinter);

[ DllImport( "winspool.drv",CharSet=CharSet.Unicode,ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern long EndDocPrinter(IntPtr hPrinter);

[ DllImport("winspool.drv",CharSet=CharSet.Unicode,ExactSpelling=true,
CallingConvention=CallingConvention.StdCall )]
public static extern long ClosePrinter(IntPtr hPrinter);
}

知道使用上面的API直接输出到打印机去，可字体怎么设置还是不知道。

你的数据可以放到word里面再打印阿...

是啊,既然word没有问题那把数据放到word中不就可以了么

找了很多资料，都没找到，要不就是使用API函数的。现在问题已经解决了。想要试验的可以将上面文件拷贝回去看看。
使用39码打印了字母，数字后，再把字体设置回来才能正确打印汉字。

发现也有不少人需要这些资料，以此共勉
