Aiieeeeedeiiieeee. That's what I get for listening to my silly friends instead of reading the law.
Your friends aren't law enforcement officers, are they?
There is no law against "printing." You can even bend over or have the wind catch your jacket and accidentally expose your gun. That's not illegal, either. The law states that you cannot intentionally show it. So accidentally showing it is okay. Intentionally opening your coat to expose your gun as a threat to someone else is not okay.
Here is the law:
"A license holder commits an offense if the license holder carries a handgun on or about the license holder’s person under the authority of Subchapter H, Chapter 411, Government Code, and intentionally displays the handgun in plain view of another person in a public place."
