I think in the octopus we have a print device that used the underlying default printer. It should be in /mnt/print or /mnt/terms/yourmachinename/print
Take a look to the start scripts to see if print is starting or printing some diagnostics. So, cp afile.pdf /mnt/print should print it there. Ah, if you don't see /mnt/print/ndb then you don't have a printer running and mounted at /mnt/print. What Lyndon said is also true, btw. I'm not saying it's not. Only that you can also wrap non-native devices with little file servers, as in this case.
