How can I tell if another App is printing Com/LPT ?

Could anyone please give me some help in monitoring the printer (and serial) ports for activity. Is it possible to read the text going through? At this point I am not interested in any "Print Manager" jobs - just text sent directly to the printer as in a Point Of Sale setup.

Any help would be appreciated.
