In Oregon and Washington state open carry is legal. "Printing" is not a legal issue. If the gun is on the belt in a belt holster and it's visible, it's legally considered "open carry."
its a little grayer than that. in WA, if you are concealing a weapon and an officer notices it he has the right to ask you to present a CPL and you have a legal obligation to show it to him. its printed right on the license.
if you're open carrying and not attempting to conceal, you can refuse to show a license or even ID and be on your merry way as the officer has no reasonable and articulable suspicion that a crime is being committed. if the officer goes beyond that, they are breaking the law and violating your rights.
i don't have an answer to the AZ equivalent though. i haven't read the state laws. the OP should do some googling and find out the answer to those questions.
