I decided to do a test print about 4 months ago at a local photography retailer. they were demo'ing a canon 6100 and said to bring in a print. Well, I pony'd up and brought in a 25" x 65" group photo. Man was I impressed when it was done, so impressed we bought the damn printer. It didn't hurt that they threw in a rebel T1i, 2 100' rolls of paper & 50% our first 3 ink purchases. On top of that they displayed it in store for the next week while continuing to demo the printer. When they were done, I called the client, had them come over for a surprise and showed them the print. Told them the story and sold it to them for $300. I know that is low, but they never would have bought it in the first place unless I made them a stellar deal. No skin off my back.
Anyways, as to the OP, I guess you can say that you can print files 24" x 65" no problem. It was a tad bit pixelated, but you had to be at least 4 inches away to see it, and no way anyone is going to be that close to a print that big.
