@sindarina @NanoRaptor They're commonly available cables with four shielded pairs in them, basically a way of ensuring cheap-ish high bandwidth cables are always available.
@sendai @sindarina thassit. And from what I understand much more likely to accept short error free transfers only presumed to go from a pc to a printer. No need to re-send cos someone started up an electrical motor on the border between Sydney and Melbourne and lost a few packets. Just a pair of 18Gbps lines to dump masses of high res cmyk data to the engine!
