Off the top of my head so check 'man dd' for all the details...

dd if=spoolfile of=firsthalf bs=1024 \
count=<spoolfile size in K divided by 2>

That should take the first half and dump it into the file called
'firsthalf'.  Then to get the other half do...

dd if=spoolfile of=secondhalf bs=1024 \
skip=<spoolfile size in K divided by 2>

Hope that works for you.
