ZXing.Net条形码二维码打印软件

C#打印 1.建立PrintDocument对象2.设置PrintPage打印事件3.调用Print方法进行打印

Microsoft .NET Framework 4.5

ZXing.Net

BarcodeWriter用于生成图片格式的条码类，通过Write函数进行输出

BarcodeFormat枚举类型，条形码/二维码

QrCodeEncodingOptions二维码设置选项，继承于EncodingOptions，主要设置宽，高，编码方式等

MultiFormatWriter复合格式条码写码器，通过encode方法得到BitMatrix

BitMatrix表示按位表示的二维矩阵数组，元素的值用true和false表示二进制中的1和0
