set your leading edge (bottom) margin to .56" (NO LESS!) and your trailing (top) to the same. Your minimum L and R margins can be 1/8" or 3mm. I always set them to 1/4".

I have always found that the Epson driver really likes to have margins set, roll or sheet. I agree with the above comment. The .56 for the bottom margin in my experience is most important. It can't be any shorter. The others I usually set at .125 inches or as suggested, .25 inches.

We aren't printing edge-to-edge.

The image we are trying to print is nowhere near the paper size -- there is at least a two inch gap on any side.

Then why not set standard margins? It saves a persons sanity when trying to use a Printer Driver in a production workflow. And I agree with you Martin, I much prefer a stand alone RIP to an RGB printer driver when it comes to production. Glad to hear you are printing. David Wollmann
