常遇到某些程序只能发送到默认打印机打印，有时需要切换打印打印不同纸张，本程序实现两个2个打印机之间切换。
初学者写的比较简单，算是给大家提个思路吧-Often encounter some programs can only be sent to the default printer, and sometimes need to switch different paper Print, the program switches between two two printers.
Beginners written in relatively simple, be it for everyone to put ideas
