TBH, if they could provide a high-quality piece of hardware that would just work for years on end and automatically reorder ink (at no additional charge, up to some reasonable limit) when it needed it for a low fixed price, maybe 50 or 60 bucks a year, I might be interested. If they added large-format print-on-demand service with quick delivery (same day in cities, 1 or 2 day elsewhere) I’d probably pay a bit more. That way I could print regular documents up to, say 11x17, at home, and have big stuff like poster-sized delivered quickly and seamlessly with the same printing system.
I just want to be able to print stuff without futzing around with a persnickety machine, and needing to replace the infernal thing every couple of years.
