（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;namespace PrintDome{ class ClsPrintLPT { private IntPtr iHandle; private FileStream fs; private StreamWriter sw; private string prnPort = "LPT1"; //打印机端口 public ClsPrintLPT() { } private const uint GENERIC_READ = 0x80000000; private const uint GENERIC_WRITE = 0x40000000;
