Sooner or later, you'll realize that debugging with print statements is slow and tedious at best and there are much better ways once you learn your way around the tools in studio. Once you discover the simulator and then add a hardware based debugger like an AVRDragon or JTAGICE II, you'll wonder how you got anything done with only print statements.
Let me know if you need code to use printf going in atmel studio. I had to futz around with that to get it
to work. Some envirnoments set up the serial port to be the default standard output device by default.
ATSAM3x is supported in Studio. If there are specific questions you can address it to sup...@microchip.com. Hope this helps. You may send your questions to me too and I will check on how best we can help
