Google cloudprint connector - Wifi enabled hardware

I'm new to 'hardware', done programming for 12 years.

I want to connect a printer to Google Printcloud (Migrate from Cloud Print - Chrome Enterprise and Education Help), with a 'connector device' via Wifi (home network) and usb connected to the printer (or maybe wifi too).

Something like BERG Cloud Bridge http://bergcloud.com/littleprinter

I looked at Arduino and alternative boards like this http://www.techhive.com/article/257343/noteworthy_alternatives_to_arduino.html

I have no idea where to start and where to find resources. Any help is appreciated!
