C# winform小票打印

（１）自定义纸张设置

 控制面板->打印机和传真->右键->服务器属性->创建新的格式

（２）自定义纸张使用

this.printDocument1.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("NewPrint", iWidth, iHeight);

NewPrint：制定一纸张名称。 iWidth：纸张使用宽度。 iHeight：纸张使用高度。

iWidth，iHeight　可以在使用过程中调整。

例如：iWidth=923，iHeight=480

（３）ESC/P指令使用

using System;
using System.Runtime.InteropServices;
using System.Data;
using System.IO;
using System.Windows.Forms;

使用例１（LPT打印）：

　printLPT.PrintESC(0);　　//打印前退纸

　printLPT.PrintDataSet(dsPrint);

　printLPT.PrintESC(1);　　//打印后进纸

使用例２（水晶报表打印）：

  this.reportDocument1.Load(Application.StartupPath + "\Temp.rpt");    
  PageMargins pMaargins;
  pMaargins = reportDocument1.PrintOptions.PageMargins;
  pMaargins.topMargin = 5;
  pMaargins.bottomMargin = 0;
  pMaargins.leftMargin = 5;
  pMaargins.rightMargin = 0;
  reportDocument1.PrintOptions.ApplyPageMargins(pMaargins);

  reportDocument1.Refresh();
  reportDocument1.SetDataSource(dsPrint);
  //reportDocument1.PrintOptions.PrinterName = "Microsoft Office Document Image Writer";

  printLPT.PrintESC(0);　　//打印前退纸
  reportDocument1.PrintToPrinter(1, false, 0, 0);
  timer1.Enabled = true;

 使用例３（printDocument 打印）：

  this.printDocument1.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("NewPrint", iWidth, iHeight);
  printLPT.PrintESC(0);　　//打印前退纸
  this.printDocument1.Print();
