说明------------------------------
^XA和^XZ：分别代表一个指令块的开始和结束, 是固定的东西。 ^PW：打印宽度，如果宽度较小，则会出现打印不全的效果。 ^MD：设置标签颜色的深度，取值范围为 -30 to 30，上面的指令将颜色调到了最深。 ^LH：设置条码纸的边距,本模板未进行设置。 以下以字符串abc^edf~L000001^L000002为例进行说明（abc、edf分别为汉字，L000001、L000002为条形码值） #CN_DATA1#：为abc的占位符。 #CN_DATA2#：为edf的占位符。 |宋体|20|15|：指字体为宋体，字符高度为20，宽度为15 ^FO：设置条码左上角的位置的坐标(70,0)。 ^BY：设置条形码显示样式, 这是该模板最重要的一个部分, 2.0是条码的缩放级别（可接受的数值：1-10点 ）,这个数值下打出的条码很小, 3.0是条码中粗细柱的比例（可接受的数值：２.0到3.0，增量０.1，对固定比例的条码无效 ）, 120是条码高度。 ^BCN：是打印code128的指令。 ^FD：设置要打印的内容 ^FS：表示换行 #ID1#：指L000001 #ID2#：指L000002 ^PQ50，10，1，Y：打印总数50张标签每个序列号只打一张。打印每组数量是10，但在每组间不暂停。 ^PQ50，10，1，N：打印总数50张标签每个序列号只打一张。打印每数量是10，每组打印后暂停。 这里可以写成^PQ1,0,1,Y，即每次打印一张，不暂停。因为打印总张数可以在程序中进行控制。

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。 ============================================================================================================== ZebraPrintHelper类代码： using System;

看看 Labelary web service,它允许您以编程方式将ZPL转换为图像.
View Code
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"); }
