I wonder if you could put a spool of paper in and print "one page" which is actually 8.5"x50' or something along those lines.

Nope. At best you'd spend a lot of time fiddling with it to get an unreliable result that'd still behave as if printing discrete pages.

Might still be cheaper than a dot-matrix machine and a box of tractor-feed fanfold would run you in 2020, though.
