What I'm using:
I have taken photos with a Canon 10D digital camera set on Adobe RGB color
profile,
I use Adobe Photoshop 6.0 for opening the file, and in photoshop, my color
settings are set to Adobe RGB (1998)
and when I print, I am printing the Adobe RGB for the print space.

What my problem is:
I have erased a small area of the photo to attempt to get a value of pure
white 255 for all three colors, and it appears white in photoshop, but when
it prints to my HP Photosmart printer, the "white" area has a tinge of
yellow beige.
Shouldn't it be as white as the HP photo paper premium glossy paper that it
is printe on?

Solutions?:
Any help is much appreciated.  What I'm trying to do is to make sure that I
accurate reproduces skin and teeth tones as accurately as possible but I'm
having this stumbling block I'm trying to overcome.

Thanks,
Chris

Have you created a profile for your monitor? (unlikely to agree with Adobe
RGB)
I use an Epson 1280, and I use the profile that Adobe or Epson supplied (not
certain which one did this).
The result is that I am quite happy with the output.
You set up the printer through the Print with Preview tab.

In your case, the printer is putting a small amount of the yellow ink on the
paper when it should not.

One possible cause for the yellow is that your monitor color temp is set too
low.  If you set it to 5000K aka D50 in Adobe Gamma, try upping it to 6500.
If it's already at 6500, you can try playing around with the monitor color
temp, but that's probably not the problem.

You could just have hosed up color settings. Check out Ian Lyons (there are
versions for each version of Photoshop, so look around a bit if you are not
using CS):

Some how, the "erasing" part of the image to get a white point seems off.

Try specifying, as per the Lyons web page, Printer Color Management instead
of Adobe RGB.
