（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

使用例１（LPT打印）：

printLPT.PrintDataSet(dsPrint);
printLPT.PrintESC(1); //打印后进纸
使用例２（水晶报表打印）：

pMaargins = reportDocument1.PrintOptions.PageMargins;
pMaargins.topMargin = 5;
pMaargins.bottomMargin = 0;

//reportDocument1.PrintOptions.PrinterName = "Microsoft Office Document Image Writer";
printLPT.PrintESC(0); //打印前退纸
reportDocument1.PrintToPrinter(1, false, 0, 0);
