Ok, I got some sleep.
BJG, the reason we keep saying printing is not illegal is because there is no law against it. The law is that the gun can't be plainly visible blah blah blah. That means printing is perfectly legal so long as the gun isn't plainly visible. The printing isn't what get you in trouble. You could never be charged with "printing".
Now if you are printing sooo bad that the handgun is plainly visible you might get hit for failure to conceal, but printing in and of itself is not illegal. Just like you might get stopped for driving to fast. Driving is not illegal but you can get a ticket for speeding. Yet we don't ever tell anyone that you could get in trouble for driving.
I completely understand that there is no statute that specifically uses the word "printing". I know that the proper charge would be "failure to conceal" if the "printing" was so obvious as to make it very clear that it was a handgun under a shirt and nothing else. A high degree of "printing" can lead to a charge of "failure to conceal". That's what I've been getting at if you look at all of my postings on this discussion thread.
