In PL 3 the print dialog permits a Caption, which is limited. Inclusion of the caption changes the Image Size within the Image Cell Size, imposing a further crop and a change of ratio, if that option is selected.
See Dialog 1:
Currently, I would propose the addition of a Custom Caption with perhaps a bit of a memory so that the Caption could reflect a subject text editable at the time of the print.
But more importantly, not change the Image Size within the Cell, rather put a footer below the image cell.
What this would accomplish would be to permit printing of an image with a caption, with better control over the image ratios.
