Hi Smiling Dog, welcome to the forum.
My question is does this still apply when printing from Qimage? When I set up the printer driver do I include the 1"?
I'm not an expert on big printers but knowing something about how Qimage works, I'm pretty sure the answer is "yes".
Qimage does not "control" the driver but uses data from it.
Qimage gets it's page size,/printable area and "native" resolution data from the driver and is what you see above the page preview on the main screen.
It's important to set the printer driver from within Qimage so it is remembered by Qimage. That's the printer icon with the red flash, 3rd in from the right at the top of the main screen.
When you get a bit more familiar, we can help to explain how to save complete printer set set-ups printer settings, paper size & type, icc profile etc. for recall later.
Terry.
