Reprint old print job?

Hi there,

Many moons ago I printed up a poster on my printer. I see it listed in my Completed jobs list. I seem to have deleted the original file. Is there any way to get this completed job back? I tried to peek into the /private/var/spool/cups directory, but I apparently don't have sufficient access priveleges (I am an admin on the computer, but I don't know enough Unix to figure out what to do next).

Any ideas?

Cheers,
Phil
