Photoshop :: CC Won't Recognize Default Printer

I'm on a Mac, I have three printers, and I want to use one in particular for a PS printing task. I fill up the printer with the right paper, then call up the file and hit "print", forgetting to notice that the assigned printer is the wrong one. So a wasted proof. So I go to Sys Prefs and set the "default" printer to the one I want, go back to PS, pick the file, hit print, and I still get the wrong printer, so I set the print dialogue box  for the right one manually, get the print, call up another file, and hit print again. The Print dialogue box has reset back to the wrong printer. Photoshop seems to have its own "default" printer selection system, independent of the overall system preferences. How the heck do I get PS to recognize and use the "default" printer, rather than settling on its own random choice?
