Silent 700 thermal paper

My experience with thermal fax paper is that printed copy is best
preserved.  I discovered a couple of years ago, that manufacturers'
faxed copies of data from the early 1990s have faded almost to
unreadability.

Not black, but faded, as with disappearing ink

Storage was in a file folder in a file cabinet in temperature and
humidity-controlled environment not exposed to light for very long at all

I've had blue-line copies similarly fade after about 40 years.

Thermofax, anyone?
