Tony-

My problem is envelopes being sealed by the laser printer.

Envelopes printed on an old HP LJ 2605dn would stick, but the flaps
could easily be loosened.

Envelopes printed on a newer HP LJ Pro M451DN stick fairly tight. The
flaps can usually be pried open, but the envelope gets wrinkled and
sometimes it pulls up the surface of the paper.

I am printing from a Macintosh with the latest system. I looked through
settings in the printer's web server, but did not see anything that
might affect temperature.

Do you know of another way to adjust temperature? I am worried that it
might prevent toner from sticking to the paper if it was lowered too
much.

Fred
You cannot adjust the temperature on all laser printers but those where
you
can
are controlled from the driver by selecting the media type (usually). Does
the
driver have an envelope media type? This may not be the smae setting where
you
tell the printer what size of paper is in the tray; it may be a different
setting where you tell the printer what type (not size) of media you are
using,
Also, make sure you use envelopes that are designed for laser printers (or
photocopiers), they have a higher temperature tolerance. If you select the
wrong "type" various things can happen like paper curling too much (common
with
smaller paper sizes because the grain runs the wrong way for instance). I
have
seen several printers ruined because people printed on to transparencies
that
were not designed for use with laser printers.

Tony-

Thanks for your insight. I am using the "Envelope" media type in the
printer setup. I wonder which choice might use a lower temperature?
I'll look for something really flimsy!

In the case of things like transparencies, I am careful to purchase
media to match the printer. I was not aware that a similar choice was
available for envelopes! I'll check with the office supply store to see
if they have some specifically for Laser printing.

Yep, another problem with lasers is having to use specialty high cost paper.
I used decent quality 20 & 24 pound bond with the Samslung Model POS I had and
it ran so hot that the paper curled. After running more than about 20 sheets,
it smelled like a smoldering incinerator full of cardboard.
You don't need high cost paper for text printing just the cheapest is fine,
where did you get that idea? What you are describing has never been documented
and I have never seen it - if it happened it was a faulty printer.

The only advantage of using laser over ink jet that I see is with the large
machines used at commercial printers and copy shops.
Cost per page for text printing is cheaper with a monochrome laser - there is
no question about that.
For home use, my money is still on ink jet.
You have said that several times and I repeat it is horses for courses. For
some things Ink printers are best for others lasers are best. It is really that
simple.

And like I say, for occasional high quality color prints, I send it to a
commercial shop.
