Glossy photo papers are generally coated to absorb less ink than matte-type papers, so a glossy paper setting will usually lay down less ink than a setting intended for a more absorbent paper.

Between glossy and semi-gloss/lustre, ink use is typically closer than it is versus matte, but the best default is still to match the printer setting to the paper you’re actually using. Using the wrong setting can affect density, blacks, and color. For example, if a more absorbent paper is printed with a glossy-type setting, blacks may look weak and colors can appear dull or washed out.

So if you want the simplest setup, use the setting that matches the paper loaded in the printer. If you must pick one default, Glossy is the more likely setting to use less ink, but print quality matters more than the small ink difference.
