So, I got the new HP Photosmart AIO Fax C309a. I was testing a bit with Advanced Photo Paper, Premium Photo Paper and Premium Plus Photo Paper. The Premiums are not in the recommended list in the printer manual. I think this is because the Advanced is water resistant with this dye inks (waterproof only with HP 38 pigment inks). But the Premium Plus is supposed to give more quality, and both Premiums better fade resistance (although the latest fade tests seem to date from 2007). Aldo the Advanced dries in 0 minutes, while for the premiums you have to wait 1 hour before touching them. For mounting, you have to wait 24 hours for the Advanced, while it's 7 days for the Premiums. But what difference do you actually see when the prints are new with 3 color dyes + 1 black pigment?
