Brusque,

I do not think you'll be able to suck that much current from the parallel
port without frying it. The max you'll get from maybe the data pins is (I
think, don't quote me on this) 1-2mA per pin. The newer port controller chips
often have IEEE-1284 Level 2 outputs, which can source 12 milliamps at 2.5V,
so maybe you can use a step-up chip?

Regards,

Tim Hamel
