How do you get the printer to print on post-its?

How do you get the printer to print on post-its? Doesn’t it stick in the printer? Size issues?

Putting a post-it by itself in the paper tray would probably be a very bad idea, but I’ve had very good results with my method. My helpers have a template: bit.ly/print-postit to create the ‘document’ and then send it to the printer as a manual feed. Then they put the actual template of sticky-notes into the printer’s manual feed tray.
