Wow, I haven't heard any problems like this before, but I /have/ heard
that Staples might have changed the paper. No, the HP photo paper is
not as thick (in fact it's /far/ too thin to be used as photo paper
and is more like brochure paper), and doesn't stand up to water too
well. When I said 'longer', I meant 10-15 minutes rather than 5
minutes.

With the HP Laser photo paper I could rub the paper off with my
fingertips. This would, however, take forever, which is why I used a
'Dobie' non-scratch sponge (safe for Teflon) and a little pressure.
The printer I used was a commercial photocopier, a Xerox DocuColor 12.
at Staples. I have been meaning to test it on other brands but haven't
had a chance yet. Even the very finest parts of the pattern I used
didn't come off unless I used a metal scraper.
I had been using Press'n'Peel before finding a laminator/paper
combination that worked well. The laser paper is $20/100 sheets,
20c/sheet; Press'n'peel is $30+shipping/20 sheets. Over $1 per sheet.
To me, that's too expensive for 'experimenting' with. I checked out
Pulsar's website quite awhile back and it looked like it might work
better than P'n'P, but they wanted to charge outrageous shipping for
it that would make it even more expensive than the P'n'P, so I never
bought it. I don't know if this has changed.
