C# 使用指令打印条形码
求打印机高人进来指点。我被这个问题困扰很久了。厂商给的技术手册，我是没大看明白，自己摸索了一周，见效甚微。 --------------------编程问答-------------------- 试试水晶报表之类的吧，指令集记得是输出流特别麻烦，而且针对的是对套打，屏蔽操作系统之类采用的 --------------------编程问答-------------------- 用字体不好么 --------------------编程问答-------------------- Code93的条形码
class Code93
{
List<int> indexs = new List<int>(20);
char[] chars = {'0','1','2','3','4','5','6','7','8','9',

'U','V','W','X','Y','Z','-','.',' ','$',
'/','+','%'};

生成条形码图片
Image TiaomaImage(string tiaoma, double wid, double het)--------------------编程问答-------------------- 生产图片
{
if (tiaoma == null)
return;
if (tiaoma == "")
return;
string s = new Code93().EndodingCode93(tiaoma);
int k = 2;
if (wid < 2 * s.Length)
wid = 2 * s.Length;
Image bp = new Bitmap((int)wid + 1, (int)het + 1);
Graphics g = Graphics.FromImage(bp);
for (int i = 0; i < s.Length; i++)
{
if (s[i] != '0')
g.FillRectangle(Brushes.Black, i * k, 0, k, (int)het - 8);
}
g.DrawString(tiaoma, new Font("宋体", 8), Brushes.Black, 5, (int)het - 8);
g.Dispose();
return bp;
}
或者用sliverlight打 --------------------编程问答--------------------
什么类型的条码打印机,使用什么端口打印,支持什么样的条码语言(ZPL,EPL之类的)
补充：.NET技术 , 非技术区
