Hi Chere, Yes, you can print on both sides of the paper without reloading, because the ET-3710 has a built-in duplexer. You can print different size photos, however, of the common photo paper sizes, only 4" x 6" and 5" x 7" can be printed borderlessly. You can also print with an expended ink tank temporarily, but we recommend refilling as soon as possible to avoid print head damage. Regards, Mark - The Epson Team.
