To print off formative statements you can do this via My Subjects, selecting the subject you require e.g. Writing and click onto Single Mark Sheet - here you can select the year of the statements you require and choose - this can then be exported and printed.
Alternatively if you go to Admin > Config > Formative Assessment Statements here you can select the subject and choose and you will then have the option to print. Please be advised this may take a while to load dependant on the amount of statements present for the subject.
