We found a roundabout way to print out rubrics - In the mark-book select a student then select marks from their Activity card. This brings up a list of all their assignments. There are icons next to the assignment and these will expand score, feedback and rubric. If you expand these you can then print out the whole list of assignments - I limit it to the page or pages with the relevant rubric. Its is a bit of a fiddle to have to do it for every student but it is a solution if you need/ want a paper copy.
