C#条码生成及打印实例代码
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
stringBarcodeString="13043404455";//条码
intImgWidth=520;
intImgHeight=120;
//打印按钮
privatevoidbutton1_Click(objectsender,EventArgse)
{
//实例化打印对象
PrintDocumentprintDocument1=newPrintDocument();
//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=newPaperSize("Custum",585,800);
//注册PrintPage事件，打印每一页时会触发该事件
printDocument1.PrintPage+=newPrintPageEventHandler(this.printDocument1_PrintPage);
//开始打印
printDocument1.Print();
//打印预览
//PrintPreviewDialogppd=newPrintPreviewDialog();
//ppd.Document=printDocument1;
//ppd.ShowDialog();
}
//打印事件
privatevoidprintDocument1_PrintPage(objectsender,PrintPageEventArgse)
{
StringBuildersb=newStringBuilder();
sb.Append("\r\n\r\n\r\n");
sb.Append("*******兴隆超市*******\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);
