let everyone in the house, office, or classroom take advantage of one centrally available printer.
Share both a printer and a hard drive, multiple printers, or multiple hard drives.
It's quite conflicting. I guess the bottom line is that you can share a printer and hard drive, multiple printers, multiple hard drives, but not multiple printers with multiple harddrives

Anyway, you got me intrested again. I wonder if the multiple drives can be mirrored?
