Printing from an iPad in schools can be a bit of a pain, especially if you don’t have any Apple computers or AirPrint enabled printers.
One piece of software I have found particularly useful is Fingerprint from Collobus. It runs on a PC and shares whichever printers you want shared to the iPads – so it can be different from the ones shared to PCs. You can also set it up so that it opens a document on the PC, a useful way of transferring a file or image into PDF format and onto the PC at the same time.
It is easy to install, costs under £7 and there is a 30 day free trial available though the trial version puts a water mark across the printout.
I think this is a good piece of software, it is under continual development and I have had no problems with it so far – much easer than setting up the AirPrint software on a PC.
