You're probably more likely to get spotted messing with your holster/gun/cover garment than by simple printing.

Check before you leave and work out some unobtrusive methods to check infrequently throughout the day--particularly after doing something that might cause an issue (getting out of the car, etc.)

In other words, make sure you've picked a good carry method and then leave it alone for the most part. Constantly checking or fiddling is far more likely to expose you than anything else.
