Hi John
Darkest print option will make everything dark which is what we don't want.
If your printer gives the options, go into graphics and select best quality print, and under Text tab set darkest settings, which will give you more toner on the text and darken text only.
Also if there is a Tab for sharpen Text make sure its not Ticked because it tends to give a sawtooth effect around the edges of what your printing.
Regards
Dave

Did you adjust the printer for the darkest print possible? There's usually a
setting from the printer control panel or possibly via the driver.

Dave's toner-transfer freezing technique
I'm not "there" yet but am getting close. The silicone based parchment paper
does give up most but not all of its toner after 10 cycles through the
laminator and 30 minutes in the freezer. I think my main problem right now
is toner density. The artwork is not a solid black. So any thin spots in the
artwork appears as thin spots on the copper. However, where there is toner,
it solidly fuses to the copper which is great.
So now I am waiting for the laminator to heat back up so I can run a better
print through it. If this does not work, I will go to a positive artwork
format so only black letters are present on a white background. Less toner
so probably it will be darker. That will mean more copper to etch which
means longer etch time. The longer the time, the higher the probability that
the toner will breakdown.
Bottom line: David's process is showing a lot of promise even though I am
taking liberties with the paper.

The test has begun. I printed out some artwork using Microsoft Word and my
HP laser printer. I'm using silicone based parchment paper. The artwork is
mostly black with white letters so the letters should etch out. I used the
"WordArt" feature inside Word to mirror image the text.
I cut out one of the four test coupons and taped it at the ends on a piece
of thin copper plate. I'm using 3M Matte Finish Magic Tape.
I then ran it through my laminator 10 times. It is now in the freezer with
21 minutes to go.
One mistake I think I made was to not tape it all the way around. Before
placing in the freezer, I saw places on the side where the artwork lifted
up. If this is a show stopper, I will clean off the copper and use another
coupon.
Using the laminator is pure genus!

That's the one Robin
As I said it does come in rolls and its quite thin so you will need to
flatten it out, if in no rush just put it between some books for a couple of
days, if urgent just run it through the laminator a couple of times
