Canon Ivy Mini Photo Printer won't print new images from Mini Photo Print App

No matter how many times I turn it off and on or charge it or restart the phone, the printer app tells me "all images have been printed successfully" when I try to send new images to the printer. 
(Yes, it has photo paper loaded.)

The husband can print to the thing using his iPhone, but my Samsung won't work (it worked fine up until this week).
