I was there, then. I remember the eco modes, however I think there was a speed benefit too so 'NLQ' really was just for posh letters to people, code printouts were in eco mode just because of the time required to print at NLQ.
I also remember the paper with tractor wheels and the possibilities for wasting paper. To print one page tended to need three sheets as the print head was some inches below the tractor wheels. To print that one page would require a form feed to get to the start of a page, another to get to the end of the printed page and a third form feed to make sure some paper was in the rollers. Brilliant printers though, I would prefer one for occasional printing rather than a dried out inkjet.
