My guess would be that the driver stores the entire rendered image in RAM before sending it to the printer. (This is technically not necessary and it would have been easy to render the image as it is sent without storing more than a few lines of it, but EPSON must have chosen the high way when writing the driver.) Printing 13x19 (inches I assume) at 1440dpi makes >500 million pixels, each of which contains 7 bits (each of the 7 colours is either printed or not), so the uncompressed rendered image sent to the printer is something like 448 MB. The driver compresses this before sending it to the printer, but with a very cheap and inefficient algorithm which doesn't actually save much space. So your 320 MB RAM don't seem that much after all. > There are no other applications open except for the Mac Finder.

Turn virtual memory on, that's my suggestion.
