It's usually a spooler issue relating to contiguous disk space available for spooling the file. It could also be the result of old files left in the spooler folder.
If the laptop has only ONE hd partition, what may well be happening is that while the PS scratch file is large, you don't have enough contiguous free space left to spool the output completely. That could cause the problem you describe as well..
