本文实例为大家分享了 C# 条码生成及打印的方法，供大家参考，具体内容如下
string BarcodeString = "13043404455" ; //条码
int ImgWidth = 520;
int ImgHeight = 120;
//打印按钮
private void button1_Click( object sender, EventArgs e)
{
//实例化打印对象
PrintDocument printDocument1 = new PrintDocument();
//设置打印用的纸张,可以自定义纸张的大小(单位：mm). 当打印高度不确定时也可以不设置
//printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 585, 800);
//注册PrintPage事件，打印每一页时会触发该事件
printDocument1.PrintPage += new PrintPageEventHandler( this .printDocument1_PrintPage);
//开始打印
printDocument1.Print();
//打印预览
//PrintPreviewDialog ppd = new PrintPreviewDialog();
//ppd.Document = printDocument1;
//ppd.ShowDialog();
}
//打印事件
private void printDocument1_PrintPage( object sender, PrintPageEventArgs e)
{
StringBuilder sb = new StringBuilder();
sb.Append( "\r\n\r\n\r\n" );
sb.Append( "*******兴隆超市*******\r\n" );
sb.Append( "品名-----数量-----价格\r\n" );
sb.Append( "精品白沙 1 8元\r\n" );
sb.Append( "张新发槟榔 1 10元\r\n" );
sb.Append( "合计： 2 18元\r\n" );
sb.Append( "---收银员：张三---\r\n" );
sb.Append( "---技术支持：李四---\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n" );
DrawPrint(e, sb.ToString(), BarcodeString, ImgWidth, ImgHeight);
