When we use SF_RTF it does not call the callback and does nothing. GetLastError() returns 2 which means "file not found" (???)
and dwError remains zero.

If we replace SF_RTF with SF_TEXT then it works but it is processed as standard text and not RTF.

I have placed a question in StackOverflow:

Re: Printing RTF using CreateTextServices()

How do we translate this to an actual printout. Going back to the original question, when using the Printer class to output a document, such as an invoice, most areas are not RTF. However, I need to include a section as part of the report that does use the RTF format. How can we use this solution to accomplish that in a printed document?
