Hi Jeff & others,
But, some where I got in a mess with my profiles and colours went to pot.
For e-mail etc. it's best to put a dot in the sRGB option as Fred said. You certainly don't need a printer profile.
See screen shot below.
If you want to make an image with some other profile, say Adobe RGB, then use the printer profile setting BUT
you must set that as the printer profile in Job Properties.
