Printing Envelope Sizes: 4 1/8 x 9 1/2

[Louis]

I am actually new to this issue assisting another developer on my team but the issue we have as I understand it is related to printing from the RadRichTextBox Silverlight control and available paper sizes.  The ideal user experience we are after is similar to what I am told Word will do which is to have x number of pages at say 8.5x11 and 1 page at envelope size in the same document and have each page print on the appropriate paper size through one single print action.  The observed behavior is that the envelope will print on the 8.5x11 paper even when the printer has the envelope available.  Also the list of available paper sizes in the RadRichTextBox does not seem to contain the 4 1/8 x 9 /12 envelope size we need.

Variation on this experience would be acceptable as long as we can print letter pages and envelopes at the same time.  It might even be better to programatically call a separate method to print the envelopes to enable things such as multiple recipients (such as 3 copies of one letter with 3 envelopes each having a different name and address).

Does anyone have any guidance on how the existing control could be extended in some way to support our needs? 

Thanks.
Louie

Hello Louis,
RadRichTextBox's document model supports single section per document, thus you cannot have pages with different sizes in one document. Multiple sections support is planned for the next official release - Q1 2012, expected around mid-February, and then your scenario will become possible.
You can create separate documents for the envelops and  print them trough an instance of RadRichTextBox. If you need to create multiple documents from a list with recipients, you can use our mail merge functionality (online demo is here).
