Toner is dry plastic powder, it won't "dry up" like an inkjet will.

I don't think there's a limit.  It depends on how long you can keep
the paper around without (1) damaging the toner, or (2) touching it
and getting finger oil on it.

There's probably some limit based on how long the paper will hold onto
its humidity before the fibers again become brittle (assuming you
humidify your paper before use, like I do), but I don't know how that
will affect results.  Mostly it affects getting toner ONTO the paper,
not off of it.
