Yep, the idea would be to allow the learner to print it (using a button set with the Lectora print page action). I’ll be including some content change actions on the page to populate the student name and completion date as well.
I hear you on the standard size. If a learner has printing setup on their tablet or phone, then I’d suspect they’d want to print the full size certificate. Not a smaller, simplified version that fits on their phone.
