Are the voltages on the transistors regardless of the output voltage on D6?=
 Can =

you get D6 to change? It seems that it is always in the low state. What hap=

if you set D6 to inverted?

Note also that you may have to set the port into SPP mode (the simplest) in=

BIOS in order to get the program to work.

Also, this will only work with a real parallel port (on the motherboard or =

an expansion card). A usb to printer port converter will not work.
