What was the problem? I have seen vague reports that the original

Still got one - it is used as a paperweight. Thankfully, I didn't buy
it, it was supplied for

Any parallel port made since 2005, at LEAST, is actually a 3.3 V port
with 5 V tolerance.

So was the G100, reminds me of that fiasco with it's special needs ;)

Hi Kirk,
there seems to be 3V PPorts also. I think on Asus MOBO AT5NM10? If possible
can you investigate that connected to a G540 please?
If someone has a schematic of the G540 (esp. the motherboard) I would be
interested.

This is the key part of his message...Sure, that could be remedied,
but the G540 would become twice the size and need another outside power
source, not really

I did not know that! I stand corrected, thanks ;-)

EPP mode is a completely different way of using the pins of the parport than
the regular SPP mode. In SPP, you have programmatic control over the values on
the output pins, and you can read all the input pins.
In EPP, those pins are driven by an additional piece of logic in the parport
control

I am throwing this out as I have run across a few people that have had
issues with EPP mode and the printer port. Now onboard parallel ports
can usually bet set to epp mode in the bios. Onboard printer ports
usually require some sort of utillity to put them into EPP mode.
