Digital BW, The Print

I am temporarily using a Photosmart 7760 while I wait for a new R220.
 Yesterday I was able to print perfectly neutral BW images, but
something has gone terribly wrong.  Today every time I try to print BW
I get this incredibly warm toned result.  I switched to the U.S.
Prepress Defaults setting in Photoshop that Clayton Jones recommends,
and have the Print Space Profile set to "Same as Source" in the print
preview window.  Nothing seems to make any difference.  The 7760 has
both the TriColor and PhotoGray carts installed.  I thought perhaps
that something had gone wrong with the TriColor cart, but I just made
a perfect color print using the same carts.  I'm at a loss to
understand how I was able to print neutral BW yesterday, and can't
come close today.  What went wrong?

I'm almost embarrased to admit this, but the problem ended up being
the paper!  I had been printing with Kodak paper, with totally neutral
results.  Yesterday I bought a box of Kirkland Professional Glossy at
Costco.  The prints using this paper were distinctly warm compared to
the Kodak paper.  The difference was so dramatic that I assumed that
something had gone wrong with either my Photoshop setup, or with the
printer.  As a newbie I am a little surprised by all of this---that
there would be such a difference inherent in the papers themselves.  I
certainly can see how color settings, driver settings, and the carts
themselves could make a difference in the print outcome.  I wasn't
counting on the paper being the culprit.

The more papers you try, the more different tones you will see from
the same inkset. Some are subtle but others very obvious. It was much
the same with darkroom papers at one time. All part of the digital
experience now :-)
