One more thing, the R1800 (I don't know stats on the rest) can take roll paper so you can do banners up to 13" wide and over 40" long, you don't have to stick with the 13x19 papers. I did one for my DD's room, it cost much less than the large wall paper murals and was a lot faster than hand painting a mural. Also you can use the 13x19 paper to print 9 4x6 photos at a time. I do this and my cost per print is just under 20 cents, which is not too bad for printing at home!
