Tried that, did not work. It must be a limit set inside Mathematica. The machine is a MacPro with 64GB RAM 512GB internal drive, so even Virtual ram has plenty of resources. Interestingly I was able to print the Selection as a pdf. Printing it to a jpeg also did work but created junk, because text elements on the plots were enlarged without enlarging the spacing in between them. I have no clue how that could have slipped through quality control at Wolfram.
