I also encountered the white dot problem with HP Premium glossy photo paper on my HP PSC 2355 printer. I even changed my printers at Best Buy, thinking that I have a defective printer, but still the same result. The pictures look good, but the white dots are quite annoying. They are virtualy imperceptible on lighter colors, but are glaring on dark colors, especially black. I would not recommend using this paper if you have an HP printer similar to mine (2355, 2175, 1315, 1350, etc.). Premium PLUS paper indeed corrects this problem, but it is almost twice as expensive. (If one looks very intently the white dots are still present even on Premium plus paper, they are just not conspicuous.) Because of this, I am now thinking of returning my HP printer, even thought the overall picture quality, as well as the product reliability, is quite high.
