C#LPT端口打印类的操作是什么呢?首先让我们看看什么是LPT端口(打印机专用)?LPT端口是一种增强了的双向并行传输接口,在USB接口出现以前是扫描仪,打印机最常用的接口.最高传输速度为1.5Mbps,设备容易安装及使用,但是速度比较慢,下面是C#LPT端口打印类的操作具体实例: /// <summary> /// LPTControl 的摘要说明,C#LPT端口打印类的操作 /// </summary> public class LPTControls { public LPT
class LptControl { private string LptStr = "lpt1"; public LptControl(string l_LPT_Str) { LptStr = l_LPT_Str; } [StructLayout(LayoutKind.Sequential)] private struct OVERLAPPED { int Internal; int InternalHigh; int Offset; int OffSetHigh; int hEve
using System; using System.Collections.Generic; using System.Text; using System.Runtime.InteropServices; namespace BarCodeLibrary { public class ZebraGesigner { [StructLayout(LayoutKind.Sequential)] private struct OVERLAPPED { int Internal; int Inter
一.EPL II 格式及打印测试 注意N命令前的换行和最后P1后的换行.将此段代码复制到windows记事本里另存为Print.ext,文件名随便,后缀为ext.然后通过cmd控制命令行输入"copy c:\print.ext COM1".然后就可以看到打印机开始打印了,效果不错. N B300,5,0,1,2,3,40,N,"1234567891123" A160,55,0,8,1,1,N,"ALP-122244444444" b420,100
