The printer supports various paper sizes, including A3, A3+, A4, A5, and photo formats like 4x6 inches and 5x7 inches. However, it does not specifically list B5, B6, or C6 sizes. For smaller sizes like 5cm x 7.6cm, you might need to use a custom or user-defined setting if available, but this is not explicitly mentioned in the standard specifications.

For photo printing, the printer supports a range of photo papers, including glossy and matte options, but the specific HP Sprocket photo paper you mentioned is not listed as compatible. It's best to check with Epson for specific compatibility or use Epson-approved photo papers for optimal results.
