That's not quite true. It's a particularly high quality of ink-jet print. You can easily tell the difference between a giclee and the output of an HP OfficeJet.
From Wikipedia (and professional photographers I've spoken to mirror this sentiment), “since [giclée] is an unregulated word it has no associated warranty of quality.” It's like “premium”.
The word "giclee" does not even appear in the description, but "inkjet" does. It's still an ordinary injet printer. It's bigger and more accurate than most. I've never seen them put in rooms so small that they'd "fill the room", I've usually seen them in rooms with several printers.
