Be able to print volunteers, mentors, hacker, judges #229
Description
When I go to /hack/[event_id] as a event coordinator, I would love to be able to have a different print option where I can select to either print the judges and/or mentors and/or volunteers and/or event countdown and also provide a QR code that will take people to ohack.dev/hack/[event_id] so that I can print this for all hackers as a welcome guide when they join us at Opportunity Hack
Think about the best way to do this step by step and update the code
