My smartphone takes photos with a different ratio from the one of the printer Canon Selphy CP1300 (10x15 cm).
When I print the photo using the "Canon PRINT Inkjet/SELPHY" app on my phone using the default
Borderless configuration, the printer cuts the photo vertically. When I configure it as
Bordered, the printer adds a big border both horizontally and vertically!
How can I tell the printer to print the photo as big as possible without cropping it (that is, with zero height border and minimal horizontal border)?
pd: if possible, without using a photo editor software to add a dummy horizontal border in order to get the same ratio as the printer.
