Can’t print glossy – Canon PRINT Review

I’ve had this app for over a year for my Canon tr4520 and today out of nowhere it had connectivity issues and will not allow me to print on glossy paper which is for labels for my business. This is so frustrating!! I have searched google for answers and I can’t find any. I’m not sure if it’s the app because if I print plain paper it works but not when I print media glossy!
