Canon PIXMA TS6420a wont let me scan or photo print from Android device

VD
Apprentice

My printer suddenly stopped letting me print this morning, I have enough ink and Ive completely reset both the printer and my app. it copies just fine but as soon as I try to photo print it says "Cannot communicate with the printer" and when I click the restore network button and do what they suggest nothing works 😞

everything has been working fine up to this point and I don't know why everything is suddenly changing, the display screen on the printer looks completely normal too, it just simply wont photo print/scan from the app on my android. please help
