Yeah, I'm curious too.
What does the report look like? Does it have bitmaps on it, for example, and the raffle information labels appear over the bitmap(s)???
It sounds like each page has the same "weight" in terms of bytes. And it sounds like bytes*25 is hitting upon some component's internal limit. Whether that component is GDI resources, RAM, HD space, etc., I don't know. But it seems that this is what might be happening. One way to test this theory is to modify the report template such that it has a lighter "weight". For example, remove a graphic or two (if it has them) and see if you can print beyond 25 pages.
I no longer think it's data because you are able to resume from where you left off and you're breaking at a page boundary.
