You can use the Database activity (Database module). It can be a simple activity with one textarea (editor) field to enter the submission text. For printing you can add css for printer friendly view and a bit of javascript to to display a button which on click will open the window print dialogue box. There should be a more detailed explanation in the Database module forum and we can offer further help there.
