If you aren't already familiar with creating bins and the bin page view, you may want to read these articles first.
First step is to create a bin with submissions. Please note there is currently a limit of 50 sources for the print-friendly view. If you need to, you can use the randomize function to create smaller bins.
From the large bin drawer view click on the bin name.
Under the "Actions" dropdown, select "Print-friendly." A new tab or window will open with the submissions displaying in a Print-friendly format.
Please note: There is a known issue if you are working with submissions on a shared project and you do not have access to the sources, you will not see them in the bin. Therefore, you will not be able to take advantage of this functionality. You can still use the print-friendly functionality from the Submission Reader or Submission profile page to print them one at a time.
