Printing is only available to devices that are attached to the Hugh Sexey network not the guest network and then only if the user has a domain username and password.

Once complete you will find you have a new icon on the iPad that is green with a white outline of a phone and a tablet. The icon will be labelled ‘Printing’ Tap this and you will be asked to enter your username and password this is the same as you use to logon to gain access to the Hugh Sexey network. There is also a check box to enable you to ‘remember me’ this will remember your credentials. WARNING if you check this and someone else uses your iPad and prints you will be charged as I doubt that the person will remember to logout and login as themselves.
