ZPL命令通过USB接口发送到斑马ZM400的简单实现方法！
点击数：1014 13:19:50　来源:
在现代条码打印机的商业使用中采用向并口或串口传送指令的方式运用越来越少，条码机厂商都选择了
方便,灵活,速度传输更快的USB接口来接收编程命令。在程序开发方面就牵涉到如何通过USB接口来传输
相关编程命令的问题。
解决方法有多种多样,首先要明确的是我们不能像调用LPT1和COM1口那样去调用虚拟的USB1口,那我们从
中选择一种最简单的方法来解决USB接口传输的问题，我们以斑马的ZM400&300dpi为例子,首先正确安装斑
马打印机机驱动,设置此ZM400为默认打印机,安装成功后在设备里虚拟出一个USB1,。最后使用C#调用默认
打印机的方式，把需要发送的ZPL打印命令赋值给一个变量，并存入相关文件,最后用C#调用打印机来打印
这个文件。在这种解决方案中就不用考虑如何通过USB传输的问题,都交给驱动程序来解决,在打印时系统会
自动通过usb端口传输EPL到默认打印机。
下面附上使用C#的实现代码:
&&PrintDocument&printDocument&=&new&PrintDocument();
&&printDocument.PrintPage&+=&new&PrintPageEventHandler(this.pd_PrintPage);
&&printDocument.Print();
&&private&void&pd_PrintPage(object&sender,&PrintPageEventArgs&e)
&&Font&mainFont&=&new&Font("Courier&New",&8);
&&string&strLine&=&String.Format("{0,0}",&&Gb.printstr);//Gb.printstr包含ZPL指令的全局变量
&&e.Graphics.DrawString(strLine,&mainFont,&Brushes.Black,&PointF.Empty);

出门在外也不愁PrintDocument.PrintPage 事件
当需要为当前页打印的输出时发生。
命名空间:System.Drawing.Printing程序集:System.Drawing（在 system.drawing.dll 中）
Visual Basic（声明）
Public Event PrintPage As PrintPageEventHandler
Visual Basic（用法）
Dim instance As PrintDocument
Dim handler As PrintPageEventHandler
AddHandler instance.PrintPage, handler
public event PrintPageEventHandler PrintPage
event PrintPageEventHandler^ PrintPage {
void add (PrintPageEventHandler^ value);
void remove (PrintPageEventHandler^ value);
/** @event */
public void add_PrintPage (PrintPageEventHandler value)
/** @event */
public void remove_PrintPage (PrintPageEventHandler value)
JScript 支持使用事件，但不支持进行新的声明。
若要指定要打印的输出，请使用
中包含的 。例如，若要指定应打印的一行文本，请使用
方法描述该文本。 除了指定输出之外，还可以通过将
属性设置为 true 来指示是否还有更多的页要打印。默认值为 false，表示没有更多要打印的页。还可以通过
来修改单独的页设置，通过将
属性设置为 true 来取消打印作业。若要使用不同的页设置打印文档的每一页，请处理
事件。 若要使事件与事件处理程序相关联，请将
委托的一个实例添加到事件。一旦发生该事件，将调用此事件处理程序。有关用委托处理事件的更多信息，请参见 。
