This application runs on a mac computer and will allow any networked printer to be used from an iPad or iPhone. It's a great deal for $20! We use it at my school and you can select what networked printers you want to use to print from iOS devices. You just need to run the application from a computer that is always on.
It's called Printopia and here is the website.
I highly recommend it if you are wanting to print from an iOS device without purchasing a new printer.
I am a Technology Coordinator at Presbyterian Day School in Memphis, TN. We are an all boys' school with grades PK-6. I help teachers in grades 1-3 integrate technology and teach students various lessons on their laptops. Each classroom has it's own laptop cart. I love educational technology and helping students and teachers! I see myself as a lifelong learner always looking for new ideas to implement with our teachers and students!
