Have a D-60 that I like very much..My question concerns prints made on a HP2000C printer When viewed in a room with incondesent lights they look ok but when you go outside in natural light or in a room with fluorescent
lights they have a green hue to them is this normal any suggestions i've tried all types of paper with the same results....

This effect is called metamerism. See explanation at metamerism (http://www.mwords.co.uk/pages/FAQ/articleMetamerism.htm).
I have the same problem with my Epson 1290. The new Epson 2200 is said to be very much better in this respect, according to first reviews.

Isn't the 1290 the UK version of the 1280?

I've never heard of metamerism using dye inks, usually just the pigment inks.

My 1270 prints look different sometimes under different lighting but only different in brightness not different colors, just like my film prints do.

Yes, the 1280 and 1290 are one and the same. A b&w print in colour mode shows the effect best. I photographed a small print with a CP995 in daylight and artificial light, setting a custom white balance for each on the white paper. This is how they compare.

(Epson inks on Epson Premium Gloss. Levels adjustment only). The artificial light half is on the left hand side. The eye is very accommodating, of course, and the magenta shift doesn't look quite as bad as it appears here.

I guess I never really looked that hard, but I checked last night and yes there is a very slight color shift under different light on my 1270 prints, I also noticed the same thing on my film prints from the lab.

Very subtle, but it's there. I also noticed that several things looked slightly different under different lighting. A blue chair, a backdrop and the cover of a book. I guess sometimes you just have to look.
