you may have reversed the height/width or orientation but I can tell you...........
YOU MUST CHANGE THE DRIVER
in your last image, you show that the 'Kind' is 'Airprint'. That is *wrong*.
Delete the printer from the system and re-do it but select from the pulldown 'CUPS' or 'Epson'.
Airprint is a braindead simplified driver for printing from iPhones/iPad
Changing the driver is the very first thing to change/try. I wouldn't doubt that the Airprint driver
has weird 'limitations' in its output
