Hi,
Greg Johnson, who is no longer on moodle.org, made a script called print.css for use in 1.9 as discussed here http://moodle.org/mod/forum/discuss.php?d=94624#p419893 Basically, you click the edit tab and go to expanded view. The script takes out all the buttons and such for editing Lesson pages.
Will that script work in 2+ ? If not, has anyone else thought up a way to print Lesson in 2+ without stuff that students don't need to see?
