noise from USB printer

[Dave Phillips <dlphillips@xxxxxxxxxx>]

Greetings:

 I hooked up my new HP 6540 printer today, it's a beauty, but it 
creates a terrible noise through my speakers when it's running. Is this 
a known problem with USB devices ? Is it a mobo problem ? (This is 
happening on my old 800 MHz machine.)

 Short of disconnecting the cable when the printer isn't being used, is 
there a solution to this trouble ?

Best,
