Media type setting with 3rd party papers

When using Canon paper on a Canon printer, you set the printer driver "media type" setting so it's the same as the paper. But when you use a 3rd party paper, you still have to set the media type to a Canon paper rather than the exact paper you're using. This feels a lot like using the wrong profile.

Then in the printing application (at least in Elements or DPP) you set the profile of your paper. So what exactly does the driver's media type setting do, and how does it interact with the profile setting in the printing application?
Thanks.

You can check with your paper provider -- they can give you a "proper" paper setting. Otherwise...well,...tr​ial and error...?

The media type setting is there primarily to inform the driver about the paper's surface characteristics which will affect its choice of dot size and volume. It can indirectly affect color in that the amount of dot spreading the driver expects will be a factor in its choice of dithering/optical blending pattern.

The Ilford Smooth Pearl documentation says to use either "Pro" or "Glossy" setting. And although they do provide their own profile, it still reminds me of how Kodak papers say to use any one of several profiles: fine for snapshots but not good if you care about color.

And since my colors are just too warm with the Ilford paper, I started thinking about this paper-type setting and wondering just what it does.

Hmmm, sounds like it's not a huge factor but still significant. And since I am having a color problem, sounds like I need to check it with both settings.
Thanks.
