Just a minor thing Barry, being a bit quick at trying to set up printing through the wizard I sometimes forget that the options offered for the interface start with the com ports so have mistakenly used a com name instead of a parallel port name.
I suppose that I should take more care of what I am doing but as most printers, apart from USBs, use the parallel port I thought it might be more convenient to list the parallel ports first, especially for old duffers like me.
