My newest laptop does not have a parallell port either, for what it is worth. To be future proof, the only way to go is USB. Can any of the cheap USB lamps be switched on/off by software?No, but USB to parallel adapters cost nothing.
128 MB USB pendrives probably cost even less. They have a light which turns on when the device is mounted. -- Herman Robak
