Yes. The Canon PIXMA TR8620a supports legal-sized paper.

Specifications:

• Maximum media size: 8.5 x 14 inches (legal).

To print:

1. Load legal-sized paper into the rear paper feed tray.
2. Adjust the paper guides to fit the 8.5 x 14 inch sheets snugly.
3. In your computer's print settings, select the correct paper size (Legal, 8.5 x 14 in).
