5.C#调用斑马打印机打印条码标签(支持COM、LPT、USB、TCP连接方式和ZPL、EPL、CPCL指令)  
搬运地址: https://blog.csdn.net/ldljlq/article/details/7338772
在批量打印商品标签时一般都要加上条码或图片，而这类应用大多是使用斑马打印机，所以我也遇到了怎么打印的问题。
一种办法是用标签设计软件做好模板，在标签设计软件中打印，这种办法不用写代码，但对我来说觉得不能接受，所以尝试代码解决问题。
网上搜索一番，找不到什么资料，基本都是说发送ZPL、EPL指令到打印机，而且还是COM/LPT口连接打印机。后来研究.net的打印类库，发现是用绘图方式打印至打印机的，也叫GDI打印，于是思路有了点突破，那我可以用报表工具画好标签，运行报表时，把结果输出位图，再发送至打印机。
后来又找到一种更好的办法，利用标签设计软件做好模板，打印至本地文件，把其中的ZPL、EPL指令拷贝出来，替换其中动态变化的内容为变量名，做成一个模板文本，在代码中动态替换变量，再把指令输出至打印机。
折腾了几天，终于把这两种思路都实现了，顺便解决了USB接口打印机的ZPL、EPL指令发送问题。
今天有点困，改天再详细讲解一下这两种思路的具体实现。
==============================================================================================================
如何获取标签设计软件输出至打印的ZPL指令？安装好打印机驱动，修改打印机端口，新建一个打印机端口，类型为本地端口，端口名称设置为C:\printer.log，再用标签设计软件打印一次，此文件中就有ZPL指令了。
==============================================================================================================
2012-06-02：发布代码ZebraPrintHelper.cs。
==============================================================================================================
2013-01-17：发布代码ZebraPrintHelper.cs，修正BUG，新增TCP打印支持Zebra无线打印QL320+系列打印机。已经生产环境实际应用，支持POS小票、吊牌、洗水唛、条码、文本混合标签打印。因涉及公司源码，只能截图VS解决方案给大家看。

//using CG, a single 8 bit character is sent for every 8 bits of graphics data. When using EG two characters
//(16 bits) are used to transmit 8 bits of graphics data, making EG only half as efficient. Since this data is
//character data, however, it can be easier to handle and transmit than binary data.
//Format:
//{command} {width} {height} {x} {y} {data}

9.在发送给Zebra打印机之前,使用.NET WinForm打印预览ZPL II命令 我有一个.NET Windows应用程序,使用ZPL II或EPL2向Zebra打印机打印命令.在直接从Zebra打印机打印之前,是否有任何方式打印预览表格中的数据？ 看看 Labelary web service,它允许您以编程方式将ZPL转换为图像.只需构建一个包含您要呈现的ZPL的URL,从Web服务器获取图像,并从应用程序中向用户显示图像. string zpl = "YOUR ZPL HERE"; string url = "http://api.labelary.com/v1/printers/8dpmm/labels/4x6/0/" + zpl; using (WebClient client = new WebClient()) { client.DownloadFile(url, "zpl.png"); }
