I'm attempting to print panoramas on an Epson R3000 connected to a Mac, using 13" roll paper. I always get a 1/4 border on the left side of the paper as it emerges from the printer. To date, I have been unable to find a detailed set of instructions for the print dialog in Photoshop for the Mac since no one takes responsibility for the print driver.
Configuration is OS-X 10.8.4, Photoshop CC.
Thanks in advance
