I display both a print icon and textual link. Just so it is clear what will be printed. The link does not actually print but displays a confirmation page which contains course info, student's name and id-number, choice answer, answer date, print date, and confirmation id (unique code to stove off falsification) formatted for printing. Students have to print it themselves.
The extra field in db is a flag to control which choice instances display this option. We have probably a dozen choices on the site but only one requires this option (another one still coming).
