Until I got the Z3100, I printed on 13x19 sheets on an old Epson desktop printer. I was able to select "Maximum Size" in the printer driver, which brought a warning message that print quality beyond the "normal" border might be degraded. I printed from Qimage, and was able to get centered prints within about 1/8" from the paper edges.
With the Z3100 and Qimage, which I use because I don't have a 3rd party RIP, I'm able to place images as I want on both sheets and roll paper. However the printer insists on a wider margin on one side of the sheet, and if I want the print centered, it has to be at a smaller size, based on the printer's choice as maximum print size.
Is there a workaround, or am I a prisoner of what HP thinks the margins should be?
