This was my first thought.
I've seen it, in a non-profit environment : using some decade old HP laser printer, with seemingly perfect reliability (compared to your typical inkjet that you need to re-buy every year if you use it seasonally), enough life left in the toner to not care about it.
Yet, the obvious "good idea" there was to print on old worthless already printed paper, just print to the other side. It's not so much the paper jams that are a problem, but all the dust, dirt and ash particles found on the old papers (those that have started lying around are even worse than those filed away for years). This gets into the printing rollers or whatever you call them and so your printer develops printing streaks, making stuff hard to read (at worse missing important things) or too unprofessional.
And then, you're stuck needing maintenance on a laser printer even though everything was okay (parallel cable, CUPS and networking, toner, printer, paper supply). Time was bought by putting a different old printer in place.
What would be needed on a regular laser printer is a warning : "Please only feed NEW printer to the paper. It's more environmentally friendly"
With that "UV paper", hopefully the printer is simplified enough and made trivially easy to clean with no special equipment. The "paper" itself needs to be easy to clean. If you don't even need contact between the "paper" and printer parts (save for feeding the "paper" in and getting it out) it might be easy enough to use even folded "UV paper" (e.g., some machines have a slot where you can put banknotes in, they work with banknotes that were folded carelessly)
