Sorry guys...thought I had it - I actually did, I got to print one lot of exam papers and then whatever happened it went back to the flashing light.
I did have one document pending and that wouldn't delete for me so I thought that was why it wasn't printing. I deleted by doing this:
typing net stop spooler into RUN, Deleting the files in C:/WINDOWS/SYSTEM32/SPOOL/PRINTERS, And then typing net start spooler into RUN. I refreshed the icon in the systray and my document pending deleted.
Still the flashing light though.
