让更多的人知道如何用C#操作斑马条码打印机
下面是我开发的条码打印程序用到的条码打印类
using System;
using System.IO;
using System.Collections.Generic;
using System.Text;

namespace Barcode
{
/*条码打印命令说明
^XA //条码打印指令开始
^MD30 //设置色带颜色的深度, 取值范围从-30到30
^LH60,10 //设置条码纸的边距
^FO20,10 //设置条码左上角的位置
^ACN,18,10 //设置字体
^BY1.4,3,50 //设置条码样式。1.4是条码的缩放级别，3是条码中粗细柱的比例, 50是条码高度
^BC,,Y,N //打印code128的指令
^FD12345678^FS //设置要打印的内容, ^FD是要打印的条码内容^FS表示换行
^XZ //条码打印指令结束
*/ //上面的指令会打印12345678的CODE128的条码
  public class BarcodePrint
  {
  [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
  private struct OVERLAPPED
  {
  int Internal;
  int InternalHigh;
  int Offset;
  int OffSetHigh;
  int hEvent;
  }
  [System.Runtime.InteropServices.DllImport("kernel32.dll")]
  private static extern int CreateFile(string lpFileName, uint dwDesiredAccess, int dwShareMode, int lpSecurityAttributes, int dwCreationDisposition, int dwFlagsAndAttributes, int hTemplateFile);
  [System.Runtime.InteropServices.DllImport("kernel32.dll")]
  private static extern bool WriteFile(int hFile, byte[] lpBuffer, int nNumberOfBytesToWrite, out int lpNumberOfBytesWritten, out OVERLAPPED lpOverlapped);
  [System.Runtime.InteropServices.DllImport("kernel32.dll")]
  private static extern bool CloseHandle(int hObject);
  private int iHandle;
  public bool Open()
  {
  iHandle = CreateFile("LPT1:", (uint)FileAccess.ReadWrite, 0, 0, (int)FileMode.Open, 0, 0);
  if (iHandle != -1)
  {
  return true;
  }
  else
  {
  return false;
  }
  }
  public bool Write(string Mystring)
  {
  if (iHandle != -1)
  {
  int i;
  OVERLAPPED x;
  byte[] mybyte = System.Text.Encoding.Default.GetBytes(Mystring);
  return WriteFile(iHandle, mybyte, mybyte.Length, out i, out x);
  }
  else
  {
  throw new Exception("LPT1端口未打开!");
  }
  }
  public bool Close()
  {
  return CloseHandle(iHandle);
  }
  }
}


如何打印中文见下：使用GETFONTHEX函数
函数使用之C#原型：
  [DllImport("fnthex32.dll")]
  public static extern int GETFONTHEX(
  string BarcodeText,
  string FontName,
  string FileName,
  int Orient,
  int Height,
  int Width,
  int IsBold,
  int IsItalic,
  StringBuilder ReturnBarcodeCMD); 

调用打印汉字，下面代码将会打印“测试”二个汉字
  string sBarCodeCMD = ""; //条码打印命令
  StringBuilder sb1 = new StringBuilder(10240);
  int i1;
  i1 = GETFONTHEX("测试","宋体","temp1",0,30,20,0,0,sb1);
