30 mb is nothing, when we create PDFs, its usually well over 100mb, often 200mb. But it's 80 to 150 pages at 36 x 48. so it is big. We print directly using the publish function with no problem until Mac OS 14.4(1). Printing to plotters has always been straight forward and easy for us. And on 4 different plotters from 4 different makers. And we also print (scale to fit) to our laser printer Tabloid extra sized, and that works great too. Again until now. But this is clearly an Apple issue. As the same thing happens in Adobe Acrobat, Apple Text Edit, Apple Pages, and various other programs.
