Posting a quick update on this, I have not had as much time to mess around with this printer as I would have liked, but the little I have done I have learned a lot. I have to print with it weekly to keep the printer heads fresh so last night I decided to go big. Most people will recommend 300 dpi minimum. Some go down to 150 dpi for canvas, but as I was curious to see what my printer would do on a low DPI and max quality settings - the below is printed @ 67 DPI.

Excuse the bad photography and lack of a frame. Total size is 36" X 80". The printer can handle 44", but I used a 36" roll. I put a green sticky note next to it for size reference and tried to zoom in for some detail. Short and skinny is the print came out amazing. This machine keeps impressing me. I will be sponsoring this site in a few weeks when I have some time to tie up a few loose ends, but I am really excited to make some frames and prints for the people on this board.
Let me know if you have any questions.
