I have a wide format printer at home that allows printing up to 329 mm wide and according to the printer properties up to 1200 mm long (that is around 13 inches by 47 inches in the local lingo, give or take a few smidgens) and has a scanner bed that will handle up to A3 size pages. It comes in handy when archiving some of those larger size pages.
I played around once and increased a A4 size model page up to A3 size just to see what the results would be. Not bad.
