点矩阵收据打印 [英] Dot Matrix Receipt Printing
问题描述
朋友们，
现在，我尝试使用点矩阵收据打印机打印收据.在收据中，每个部分均应以不同的字体大小和两种不同的颜色打印.谁能帮我这个忙.

Hi friends,

我尝试了ColorSet方法来更改文本的颜色.我没用.
有人可以帮我吗?
在此先谢谢您
I''ve tried the ColorSet method to change the color of the text. I it didn''t work.
Can anyone help me on this?
Thanks in advance
推荐答案
您正尝试发送本机原始打印机命令，因此请转到打印机用户手册并了解目标打印机支持的命令语言.可能是ESC/POS
因此，去学习使用什么ESC/POS命令来设置字体大小和颜色.
您的ColorSet方法没有意义！！！它正在设置与目标打印机不相关或不相关的Console对象.
You''re trying to send native raw printer commands so go to the printer user manual and learn the command language your target printer supports that it''s likely to be ESC/POS
So go and learn what ESC/POS command is used to set font sizes and color.
Your ColorSet method does not make sense!!! it is setting up the Console object that is not related nor associated to the target printer.
我已经有了一些转义码，并且可以正常工作.
I''ve got some escape codes and those working fine.

Anyway thanks for your ideas and time.
一个非常现成的解决方案:
如果您使用的是.NET
以及是否有用于点矩阵打印机的驱动程序
使用2D绘图工具创建收据.
这实际上是用图形类处理的颜色和字体打印图形，然后您可以使用任何字体而不必担心打印机支持的字体.使用驱动程序进行颜色处理也应该起作用.
但是，这对您的可用资源做出了很多假设.
A very off-the-cuff solution:
If you''re using .NET
and if you have a driver for the dot-matrix printer
Use the 2D Drawing tools to create your receipt.
This is, effectively, printing a drawing with the colors and fonts handled by the drawing classes and you can then use any fonts without worrying about those supported by the printer. Color handling, with the driver, should also work.
But, this makes a lot of assumptions about what you''ve available.
