Printer Info in HP-UX

I’ve had this problem before and like an idiot didn’t document what I did so I need to ask the question again. I am not very Unix savvy and I need to get some information out of our old UNIX server and am having printing problems. I think it stemsfrom me not having any more disk space. I know I was able to clear out some files in a sort of printer control area, but can’t find it again. Or just any info on how to clear up space would be great. Thanks.
