I read your article regarding curling paper from laser printers. Though I
cannot speculate on the causes for your laser printer, I can give you
an idea on what we are seeing and doing about it. Suffice it to say, we do
not have a great problem with curling.
We have a large series of laser type printers. Apple LaserWriters, HP LaserJet plus, Imagen I300's, Apple NT2's, and versatec plotters. There is a slight
amount of curling that occurs because of the extreme heat required to fuse the
print, in combination with the paper rollers. I suspect that all Cannon
engines, because the rollers, will have a problem with curling. We have an
IBM 3812 that does not have extreme heat. The lack of inherent curling is
offset by it being impossible to write drivers for it.
We have been maintaining our paper stocks in a humidity controlled environment.
If the paper is too dry, we have a problem with streaking because the ink does
not fuse properly. If the paper is too wet, I suspect that the slight amount
of curling would become a greater problem. We never had the curling problem
because we noticed a molding problem.

PS We have a LaserJet Plus and we are trying to get it to do troff output.
Can you point me to the correct source for filters? We are running this off
of a BSD spooler.
