说明：  一个利用微软的RichTextBox控件设计的打印预览源代码，支持所见即所得打印，支持文字图片，和word一样（因为本身RichTextBox都支持，呵呵），支持直接打印输出和预览，反正预览的一切功能都可以做到，特别适合对打印要求不是很高的朋友，初学者也可以从中学到一些打印控制的支持，代码不错。
(A RichTextBox control using Microsoft' s designed Print Preview source code, support for WYSIWYG printing, support for text images, and the same word (because they are in support of RichTextBox, huh, huh), in support of direct and preview printouts, anyway preview All functions can be done, particularly on the printing requirements for a friend is not very high, beginners can learn the support of a number of print control, good code.)
