"If you're printing a high-bit file directly from Photoshop, it's both unneccessary [sic] and unwise to downsample it to 8 bits per channel prior to printing. It's unnecessary because Photoshop is smart enough to downsample the data before handing it off to the printer. It's unwise because if you request color space conversions, you'll get better results allowing Photoshop to do the conversion on the high-bit data before it does its automatic downsampling than you will forcing Photoshop to make the conversion on an image that's already been downsampled to 8 bits per channel."
