Currently RadRichTextBox supports Html-based and Silverlight printing.

Silverlight printing should be very exact as it simply prints out each page as an Image. Though this type of printing can be really slow for large documents.

Currently page layout in Html printing depends on browser layout and this is why the number of pages in the actual document and browser-printed version can be different. Using absolute positioning in Html hopefully this issue can be resolved and paging/positioning of document elements will be precise.

Implement a mechanism that allows embedding font data when exporting documents.

Many common words with apostrophes fail spell checking (isn't, shouldn't) while others pass (don't, can't). 

Word traversal (GetCurrentWord, etc.) breaks words apart on apostrophes.

- When exporting Docx to Binary,  non-breaking spaces are being replaced by a normal space.
