What does the ? mean exactly when I try to select a photo to print and it rejects. Is the picture too low a resolution ? I seem to be able to print only above 2 MB but don't see anything about this in documentation only must be EXIF.

Just saw an earlier post about this subject. I am also using a USB . To my knowledge the pictures have not been edited. I just noticed one pic which worked was only 158 KB whereas the rest are all over 2MB. All have been taken from a phone and emailed to a PC.
