打印店黑白打印要0.15一面，彩色1块一页，价格差的很多，课程作业和论文里只有一部分有图需要彩色打印，直接全按彩色打印的话会贵上不少。
原作者开发了 “ColorPdfSpliter” (https://github.com/huuhghhgyg/ColorPdfSpliter)，支持单面和双面打印模式，双面打印会把本属于同一张的页码分在一起，方便拿去打印店打印。原作者描述：
“可使用duplex参数实现双面打印时的彩色与黑白分割。这个参数保证生成的彩色与黑白文件均为连续的两页（即一张纸上的双面）。当一张纸上正反打印的两个页面中有一个为彩色，则这两个页面都会被划分入彩色文件。”
提供的本地部署版需要安装python环境，对一些小白用户有难度。
因此，在原作者的基础上使用 Qt+PySide6 做了个界面，解压后直接使用，支持
- 输出到PDF同目录 / 指定同一目录；
- 单面打印/双面打印添加多个文件同时处理，PDF不必放在一起
单面打印模式：
双面打印模式：
