We are working to make printing easier from the BYOD network. We have found some wireless print servers that will enable us to bridge to a limited number of printers at each site.
On iPads/iPhones/iPod touches, press the little arrow to the left, press "Print" then "Select Printer". Pick one from the list.
On OSX, just go to printers, at least 1 school printer should show up.
On Windows, you'll need to install the Bonjour Print Service (it can be downloaded here: http://support.apple.com/kb/DL999). Once it's installed just run the Bonjour Printer Wizard and set one of the printers up like you would any other printer.
