        }

推荐答案

这实际上取决于打印机功能。如果是基于文本的打印机，则需要输出ESC / POS命令（对于大多数Receipt打印机）。如果打印机是光栅打印机，那么你可以像上面那样打印位图，但当然你需要格式化它。



无论如何你建议你寻找一个用于e / pos的图书馆或用于为你努力工作的光栅报告工具。



（例如GitHub上的ThermalDotNet（e / pos）或类似内容） 。

It really depends on the printer capabilities. If it's a text based printer you'll need to output ESC/POS Commands (for most Receipt printers). If the printer is a raster printer then you can print a bitmap as you have above but of course you'll need to format it.

I suggest in either case you look for a library for e/pos or reporting tool for raster that does the hard work for you.

(E.g. ThermalDotNet (e/pos) on GitHub or similar).

如果您的打印机具有图形模式并且您已安装驱动程序，请使用2D .NET图形工具。



最通用的方式：

• 打印任何装饰顶部

If your printer has a graphics mode and you've the driver installed, use the 2D .NET graphics tools.

Most General Way:

• Print whatever will be your decorative top

• 打印行项目，总数等。

• 打印装饰底部
