C# ESC

具體內容大家自己看！如有好的解決方案大家共同研究！ （１）自定義紙張設置 控制面板->打印機和傳真->右鍵->服務器屬性->創建新的格式 （２）自定義紙張使用 this.printDocument1.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("NewPrint", iWidth, iHeight); NewPrint：制定一紙張名稱。 iWidth：紙張使用寬度。 iHeight：紙張使用高度。 iWidth，iHeight　可以在使用過程中調整。 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"; //打印機端口 public ClsPrintLPT() { } private const uint GENERIC_READ = 0x80000000;
