One of the things we constantly struggle with is prioritizing time on the printer. The kids are always in the room at recess, lunch, passing periods, even occasional weekends... trying to get prints started. We've tried (1) first-come-first-served, (2) Google Doc sign ups, (3) Hunger-Games-style (last kid standing uses the printer), (4) dry erase board sign up.... but nothing has stuck yet.  

Below is our newest attempt at managing the workflow on the printers. The idea is that when the printer is idle (which is getting rarer and rarer these days), the kids and/or I can grab a sheet and run a few prints. 

Does anyone have advice on a good system that works?
