This is a pretty cool trick to use if you have printed something to the wrong printer. Especially if the printer is turned off or is in a remote location at work or something similar. You can just move it to another printer. I tried it on my home printers (I have an inkjet and laser) and had mixed results. If you print to a laser first it will probably print too fast to make the switch, but it did work for me if I printed to my inkjet first. They have quite slower printing speeds.
