Ok, that is what I figured. Here is another thing.
We ran print last night unattended and one of the drawers ran out of paper (to print ID cardS) so it stopped. We came in this morning and added paper and it restarted to the beginning. Is there a timeout value or something that can be set to keep it from restarting at the beginning of print?
