hello, I have a problem when printing panoramic photos with my Epson 4800, the size of photos are 20*105 cm, but once you set the paper, the printer printing on A4
while with photoshop preview is correct, any ideas?

The paper is set correctly, the firmware is updated with the latest in home epson
(A_0057A), to print photos in A2 it no problem for others, the more prints on a roll
A2 not a long run.
(P.S. i'm not write English very well, sorry)
