Removing installed updates

Hi everyone

Just wondered if anyone can help me with this: I just installed updates on my Mac (OS X 10.6.4), and I noticed it has updated printer software for a Canon and an Epson printer, neither of which I use any more (they were friends' printers that I just connected to on one occasion to print).

I've attached a screenshot of the Software Update window that displays the updates, but I was wondering if anyone can tell me how I can remove the updates and the printer software completely? There's no Windows-style "add or remove software" as far as I can tell, and the printer software isn't in my applications folder.

Any help appreciated!

Thanks

My 2 printers take up very little room, is it worth worrying about?
Look in your user library for the files;

Thanks Collin... I'll look into that. You're right though, I could just leave them on... but I'm rather OCD when it comes to my computer's file organisation!

Thanks again
