打印条形码 [英] print BARCODE

问题描述

我正在开发一个用VB6编写的现有项目，现在我需要在其上进行条形码打印.我已经为它编写了代码，并且当打印机连接到我的开发机器上的串行端口时，它可以正常工作.

问题在于客户端计算机中没有串行端口，而只有USB端口.当我通过USB端口连接打印机时，没有任何反应.我想对代码进行任何更改以使其实现吗?

I am working on an existing project which is written on VB6 and now I need to encoorporate barcode printing on it. I have written the code for it and it is working well and fine when the printer is connected to serial port on my development machine.

The problem is that in the clients machine doesnot have serial port but is having only a USB port. When I connected the printer through USB port nothing is happening. Am I suppose to make any changes on my code to make it happen?

Hope it helps you

1)使用免费的条形码字体，例如"9之3".

2)搜索Codeproject.这个问题以前已经问过很多遍了.

3)获取所需条形码类型的规格并自己绘制条形码.

4)最重要的是:了解如何使用Google！

1) Use a free barcode font, e.g. "3 of 9".

2) Search Codeproject. This question has been asked many times before.

3) Get the specifications for the desired barcode-type and do the barcode drawing yourself.

4) And most important: Learn how to use google!

这个问题尚不清楚.您是否有打印机连接到USB?是否安装了条形码字体?为什么使用VB6，几年前它已被VB.NET取代.

This question is not clear. Do you have a printer connected to the USB? Do you have barcode fonts installed? Why are you using VB6, it was replaced by VB.NET years ago.
