Printing Warning: Documents containing more than 2 gigabytes of data may not print correctly

Printing Warning: Documents containing more than 2 gigabytes of data may not print correctly...

I am having a problem trying to print a 44 inch by 60 inch image file that is 600dpi. The file size size is 2.66 gigabytes and when I send the image to the printer, after it telling me various things, it tells me this: Documents containing more than 2 gigabytes of data may not print correctly. And the warning is correct... for the lasts 13 inches of my 60 inch image... for whatever reason Photoshop takes the first 6 inches of the image and it pastes it on the far right of the image twice and then pastes the first inch of the six inches the final time so the size comes up to 60 inches wide. (or high since I'm printing the horizontal image vertically on my 44 inch Epson 9900. This paper cost me $60 a shot. So printing a bunch of times is out of the question. 

What would cause Photoshop to steal the first six inches of the file and randomly place it 2.2 times at the end of the file? And - how does one prevent this from happening?
