To clarify further, if you select a profile in the Color management tab, the color management in the printer driver should get disabled automatically and you really shouldn't try to force the driver to use the profile as you will mess this process up and get bad prints. You should see a greyed out choice in the color management tab in the printer driver. You do need to figure out what paper settings in the driver the profile was created for as it will only work correctly when you have the exact right driver settings set. Usually the paper or the profile comes with a set of instructions for using the paper in your printer that has that info.
Thank you for your reply and insight. I’ve been using Epson papers with my Epson 3880, and what appears to be the exact Epson paper names appear in Lightroom’s printer settings (e.g. - Enhanced Matte Paper; Velvet Fine Art; etc.). On Canson’s web site, I found the Epson equivalent printer settings to use for their papers (e.g. - Select Epson’s Enhanced Mattepaper for Canson’s Art Photographique.).
