⛏ use system print function

看到你在 v2ex 这个讨论 上说会调用浏览器打印方法，但实际上你放的是个链接，这个 pr 里调用了 window.print 方法，而且用 id 指定了打印的内容，虽然我看你 css 上已经针对 print 做 media query 了，但如果页面里还有没有匹配到的元素还得添加样式规则

I recommend that one shall always produce PDF on his/her own and this may remain the default behavior. Consider that a visitor may simply use Command-P when he/she would like to print or create his/her own PDF; then the pre-produced PDF can be a good complementary which allows the carefully designed visual details (e.g. typography) to be preserved.

Additionally, please use English instead for a better international communication environment; nonetheless, I appreciate your kindness.
