* The connection between LPT pin 2 and pin 15 is used for autodetection by
some systems, while others don't need it.
* For safety, connect Ground line to all LPT pins 18-25.
* Note that the colour coding is rather arbitrary (does anyone have a better
coding?). It is only meant as a mnemonic during soldering.
