Hello, I have enjoyed learning from this forum. This is my first post.
The P800 manual implies that only those sizes in the drop-menu that have Front Fine Art option can be used with the FA Loader.
7x10 inches is not a choice in the menu.
However, I did manage to get my custom page size all set up fine with Front Load, right Media, etc., in the Driver, but have not yet tried to print, lest I mess up.
Thanks for your advice,
Sonny
