I didn't think to write down any code that may have come up, but here are the conditions;

I'm printing from a batch plot file. All drawings in that batch plot are from model space. The print options are extents, fit to page, and monochrome.

Simple right lol?

No one else has access to these dwg.s at the same time i could be printing them and it's only 12 drawings.

I do remember it saying that it's a program error with the usual "report this to autodesk" window poping up.

I'd be grateful for any ideas you might have.
