Distinguishing printers of the same model

[Ryo Furue]

Hi,

When I try to add a printer: http://localhost:631/ > "Administration" > "Add Printer", I see a lot of printers under "Discovered Network Printers":

HP Color LaserJet 4700 [5E214B] (HP HP Color LaserJet 4700)
HP Color LaserJet 4700 [5E214B] (HP HP Color LaserJet 4700)
HP Color LaserJet 4700 [E2C705] (HP HP Color LaserJet 4700)
HP Color LaserJet 4700 [E2C705] (HP HP Color LaserJet 4700)
[. . . a lot more . . .]
HP Color LaserJet 4700 (HP Color LaserJet 4700)
HP Color LaserJet 4700 (HP Color LaserJet 4700)
hp color LaserJet 4600 (HP color LaserJet 4600)
[. . . some more . . .]

I'm wondering how I can tell which is the one sitting near my office.  We have four example of the same model on this floor.

I know its DNS name and IP address, so I can access to it on a webbrowser by going to "http://dnsnameofprinter.example.com/", but I don't see a number in the above like "[5E214B]".

Cheers,
Ryo
