I have tried setting custom paper sizes to 32.9cm wide and 158cm long (I have even tried setting length to less than 110 cm in case the old wives tale of 44 inches has finally become true). Something has changed in the Mac/EPSON printing chain, and I am as yet unable to crack the code to find out what. Plus I originally printed on 10.5.8 and now I am using 10.6.5. Only trouble being I now use an R2880, and it really doesn't want to play. I know it can be done, because I have the original to look at, and someone wants to buy a copy. I am trying to reprint a pano printed originally on an R1800 - 32.9cm wide by 158cm long.
