What is Qmaster and Qadministrator?

I need some advice about two applications that suddenly appeared in my application folder. Qmaster and Qadministrator. I see that they are Apple programs, but don't know how they got there (though they may have come as part of some other programs I recently installed) nor do I know how to use them or if I really need to use them. I see that there is a referrence to networking, but I am not on a network per se (other than a router connecting my desk top Mac to my Macbook.

I searched the forums and can't seem to find what this does, how it got there, and how it works.

Thanks.
