How can I print GtkTextBuffer using GtkPrint ?

["Miroslav Rajcic" <rajcic sokrates hr>]

I want to support printing in my application using GtkPrint.

Is there a simple way to print the contents of the GtkTextBuffer (containing multiple fonts, colors and other 
formatting)
using the GtkPrint ?

Do I have to write the code that draws the text manually ?
Is there any complex sample code that could help me ?

TIA,
  Miroslav
