What is the smallest All-inOne wireless printer out there? -

I d like to buy an All-In-One printer for my house, but the space is limited. I d like it to be wireless to print from different laptops. So, what is the smallest AIO printer out there? Thank you very much for your answers.

Wireless is easy to get, just put in a small printserver box and link it up to your wireless router. Less than $100 to turn any printer into a network printer.
