I recently upgraded to a 27 inch iMac running ML. I had downloaded epson14751.dmg (printer driver V9.04) when I was still on SL on my 2007 21 inch since it was needed for ML. To get it to print using the new iMac, I had to reinstall epson14751.dmg and everything seemed fine.
As long as I print with no offset to the paper (Hannemuhle Baryta) it prints fine (top=0, left=0). As soon as I offset the image it prints as below. Since I do a lot of test prints, often running the same sheet through a number of times, I rely on the offset to print multiple times on the same sheet when testing color, sharpness, etc.
Any ides on what's happening here? This is supposed to be a flower...
I also aligned the print heads, thinking that may affect ti. It still does the same thing.
