>Of course this need not necessarily rule out the use of these printers.
I agree

I guess it would

One month was not long enough anyway, but I must admit they behaved very good in a 100% humidity environment. Twelve wax-prints (130x180 cm) in a very wet cave, with mushrooms on the ground. The iron bars which were holding the prints straight were very damaged, but the paper after drying (the prints are now safe) has found back its original shape.
For this exhibition we choose the best quality paper the lab was able to treat.
