You can tell a rich edit control (CRichEditCtrl) to render its output for a specified device, such as a printer. You can also specify the output device for which a rich edit control formats its text.
To format part of the contents of a rich edit control for a specific device, you can use the FormatRange member function. The FORMATRANGE structure used with this function specifies the range of text to format as well as the device context (DC) for the target device.
After formatting text for an output device, you can send the output to the device by using the DisplayBand member function. By repeatedly using FormatRange and DisplayBand, an application that prints the contents of a rich edit control can implement banding. (Banding is division of output into smaller parts for printing purposes.)
You can use the SetTargetDevice member function to specify the target device for which a rich edit control formats its text. This function is useful for WYSIWYG (what you see is what you get) formatting, in which an application positions text using the default printer's font metrics instead of the screen's.
