如何快速多次打印Photo

Question

各位大拿，

在实现Photo打印时，有一种异常Case，就是需要快速的多张打印，目前使用了数量级为100所有的Photo进行快速多次打印，

这种Case操作程序会抛出异常。请大拿支招，是否有方案修改该问题，（PS：不考虑简单的TryCatch）

Answer 1

Hi，

没太明白您的意思，您是sample运行不出来还是怎么样，你对这个sample做了某些修改吗？您具体想实现什么，能不能详细的描述下呢？

Answer 2

你好，

就是每次让其打印100张，并且多次打印。

对sample一次可打印的阈值进行了修改，使其可以一次打印100张。

Hi LiangliangWang,

你的意思就是Copies数量为100么？参考下： 如何更改打印预览 UI 中的标准选项

printTask.Options.NumberOfCopies = 100;
