When printing the class list after a week or more of classes have occurred, you can only print the current month, the next month, or the class roll sheet from the week you are printing onward. I would like to request that you be able to print a new roll sheet for the weeks that have already occurred in addition to the current and upcoming weeks. When we need to reprint roll sheets due to students enrolling late, we no longer can see the previous weeks and mark these.
You can edit when roll sheets start printing under More > Settings > Roll Sheets :)
