C#调用斑马打印机打印条码标签(支持COM/LPT/USB/ZPL/EPL/Bitmap)

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。

/*
ColorDepth
图像输出支持的颜色范围的像素深度。有效值为 1、4、8、24 和 32。默认值为 24。仅对 TIFF 呈现支持 ColorDepth，对于其他图像输出格式报表服务器将忽略此设置。
注意：
对于此版本的 SQL Server，此设置的值将被忽略，且通常将 TIFF 图像呈现为 24 位。
Columns
要为报表设置的列数。此值将覆盖报表的原始设置。
ColumnSpacing
要为报表设置的列间距。此值将覆盖报表的原始设置。
DpiX
输出设备在 X 方向的分辨率。默认值为 96。
DpiY
输出设备在 Y 方向的分辨率。默认值为 96。
EndPage
要呈现的报表的最后一页。默认值为 StartPage 的值。
MarginBottom
要为报表设置的下边距值，以英寸为单位。您必须包含一个整数或小数值，后跟“in”（例如，1in）。此值将覆盖报表的原始设置。
MarginLeft
要为报表设置的左边距值，以英寸为单位。您必须包含一个整数或小数值，后跟“in”（例如，1in）。此值将覆盖报表的原始设置。
MarginRight
要为报表设置的右边距值，以英寸为单位。您必须包含一个整数或小数值，后跟“in”（例如，1in）。此值将覆盖报表的原始设置。
MarginTop
要为报表设置的上边距值，以英寸为单位。您必须包含一个整数或小数值，后跟“in”（例如，1in）。此值将覆盖报表的原始设置。
OutputFormat
图形设备接口 (GDI) 支持的输出格式之一：BMP、EMF、GIF、JPEG、PNG 或 TIFF。
PageHeight
要为报表设置的页高，以英寸为单位。您必须包含一个整数或小数值，后跟“in”（例如，11in）。此值将覆盖报表的原始设置。
PageWidth
要为报表设置的页宽，以英寸为单位。您必须包含一个整数或小数值，后跟“in”（例如，8.5in）。此值将覆盖报表的原始设置。
StartPage
要呈现的报告的第一页。值为 0 指示将呈现所有页。默认值为 1。

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。
