What does the "princess" in the bar mean?

The occupation of pouring wine and ordering songs in KTV/nightclubs is the waiter.

KTV and nightclubs generally have the profession of princess, but KTV and nightclubs have nothing to do with DJ at all. Now KTV and nightclubs especially like to add the word DJ in front of the princess, which is what some people call it.

In the early days, it was called Princess, but now KTV and nightclubs seem to have spread this wrong name into jargon. Obviously, these nightclub princesses and KTV princesses can't play CDs at all, and they are completely different from DJ who plays CDs in nightclubs, bars and other places. They are not DJs at all.
