Bob, Let me ask you a question about this. It appears that, according to this, this limit is a PS limit, not an Epson driver limit. That's odd though...because no matter how many PPI I send to the Epson driver (or Piezo driver), it won't print more than 44"...but that wouldn't make it a PS limitation, but a driver limitation. It appears that the limitation is in the driver, and is the 30k divided by the resample resolution, and has not a thing to do with the resolution you send it. What's your take on this? If they just matched the PS limit that makes no sense to me. Austin
