Crashing during printing

[shaosean at unitz.ca]

I've created a stack is used to create multi-page documents (hundreds and thousands) and 
whenever I try to print it makes it up to "Processing Page: 129" and then crashes. This is 
happening in standalones, as well as in the IDE (stopped and running).

Anyone else having problems printing huge documents? Each card is one 8.5x11 sheet of paper 
(it's all been worked out).
