Qt打印--输入信息生成模板发送到打印机

    最近看了一些Qt方面的东西，老师让我们做一个输入信息生成模板然后发送到打印机进行打印得Qt程序，Qt4、5都有QPrinter类支持跨平台的打印。

    先看下效果图吧，运行的时候在这里能看到窗口，自己在ui界面加上去的窗口，这是自己设计的模板，是个个人信息模板吧。

         

    点save，则会保存为pdf文件，打开后是这样的，不会画表格，先从简了

    

        点print，是这样的

    

    可以选择打印机，也可以使用网络打印机，用的是printDialog类

    贴一下代码吧

    先在.pro文件里加上打印支持

    QT += printsupport
