Noise is there whether the printer is turned on or not. It disappears
only when one or another of the cables are disconnected.

The printer is plugged into the same strip as the machine.

I tried lifting the ground, the noise was undiminished.

Next I'll try reprioritizing the interrupts, as soon as I can get
irqtune built. Or is there other software I should try ?

Linux 2.6 kernel, Debian Etch.
