If you navigate to /Library/Printers, you'll see folders for Canon, Espon, and HP printers. There's no real need to keep the printer drivers lying around for printers you don't have, so you can remove the extra folders to free up some drive space. Since these folders are owned by root, you'll need superuser status to delete them.
Once you cd /Library/Printers, you can just type sudo rm -r [directory_name], where [directory_name] is one of EPSON, Canon, or hp (do NOT type the square brackets). Note that if you do this, future use of any of the deleted printers will (obviously) require re-installation of the drivers. Use at your own risk, but my Canon and hp driver folders have been gone for weeks with no real problems.
