Printer says " WRONG DIMENSIONS" Why?

You export it at 96dpi.

glad we all agree on that, given that you work up not down and are not using low res images in the mix

What matters is the pixels size of the image.

no dispute there either, whichever way you actually do the math


I'll leave the rest of it to you experts
