In a lot of states, open carry is not legal, so concealed REALLY means concealed - you can get into a lot of trouble if someone sees your firearm. Here in Utah, open carry is legal (at least for the present time), so if you are 'made' it's not a big deal as you are not breaking any laws, however, you still may have people overreact. Mainly the depth of concealment depends on you. How comfortable are you with your firearm, where are you going, and what you prefer. There are tactical advantages to concealing with nobody knowing you are carrying, but there are societal advantages (criminal aversion to committing crime around a person with a firearm) to open carrying.
Don't worry about printing, unless your employment is at risk, do what feels comfortable and allows you ready access to your firearm.
