Parallel port problems
It is possible that the parallel port in your PC is
simply not working. If possible, run LUSAS on another computer with the same dongle/ key combination. If this works it proves that the parallel port is the problem. The parallel port
may need to be replaced. If it does not work, it is possible that the dongle is corrupt.
Some printers cause the dongle to malfunction by
grounding to earth pins which are used by the dongle but
not used by the printer. Problems have been encountered with a small
number of HP and Roland plotters. The dongle will normally work if the printer is powered
up before the PC is turned on. Alternatively you may need to
remove the printer cable and reboot the PC before running LUSAS.
