I have the Epson 4800 and have always printed on cut sheets. Recently I've had a request to print a pano that's about 49 inches long. What are the limitations on length? Printing will be from either PSCS4 or LR2.
There are no limitations on length. I regularly print panos that long on my 4800.
Just buy a roll of paper and print away.
BYW, there is no need to print sheets if you can find a roll of the paper you like. Rolls are much cheaper per print. The cutter on the 4800 is excellent.
