Then have her OLCI and get the BP from the gate agent. Just tell them she came in on another carrier and she needs her BP. OTOH, if she's late enough not to be able to checkin there's a good risk of being too late for the flight even with one.

Without knowing the airports, airlines, and and even the flight numbers, a definitive answer to your question is impossible.

In the simplest situation where I have the boarding pass for the second ticket, both tickets are domestic, and the flight for the first ticket arrives in the same concourse, I don't have to be re-screened. I've done this many times.

There was one time when I had a flight on United and another on SouthWest. I bought the SouthWest flight while in the concourse, but the online check in wasn't working. So I had to walk the gate to get the boarding pass. The SouthWest agent would not issue me a boarding pass until I prove how I got to the secure area. I showed her my United boarding pass.

You say TSA, but sometimes people use the TSA as a generic term for airport security screening. In many countries, the experience of arriving at the airport on a domestic flight and strolling to the gate for a connection does not exist. In India and some other Asian countries, every arriving connecting passenger has to go through security screening. Which pretty much kills the airline hub and spoke business model.

Had that once on a quick turn segment run. Walked off a plane, 20 minutes later went back to the GA at the same gate and asked for a BP. She wondered the same, i.e., how I got into the secured area without one. Told her I had just walked off that plane, but that they didn't issue me a BP at the first airport, so I needed to get it here. She was confused, so I explained that I took the flight in order to get the last 2 segments I needed for my status. She was even more bewildered at that, but finally issued my new BP.

OP - As you can see, there are a Zillion (possibly only 3.45553 Billion) permutations to a very simple question with a very simple answer for your wife's specific situation. Transferring at PRG may not be relevant if you are doing a domestic transfer at ORD on UA.

But, in order to give you a definitive answer to that simple answer, we need:

1. What airport are we talking about?
2. Arriving carrier / arriving from / flight #
3. Departing carrier / departing to / flight #

At that point, barring some massive problem which could affect any traveler, it will be easy to provide a simple answer.
