As your printer is not a pro printer, I rather suspect that the ink manufacturer will not necessarily have a broad range of ink / paper profiles avaialble, which means you will likely have to develop custom profiles for the ink you are using for each different paper type. You should check what is supported on the ink supplier's website.
I found for my printer (Epson 3880), the only time I let the printer set the colours is when I am printing B&W as I find that the Photoshop colours have a bit of a green overtone, whereas the printer management gives me true black. I use the Epson inks so if I use Epson paper, the profiles are built into the printer drives and if I use third party paper (I sometimes use Moab paper), I can go to the Moab website and get the appropriate ICC profiles for my printer / paper combination on line and download and install them.
