I've been printing on Epson premium luster with my Z3100, after making a profile with the built-in i-one (base model, no APS). Results are excellent, with very deep blacks and color accuracy that certainly meets my expectations. Shadows are just a little dark, which seems to be standard for the profiles my printer generates; a subtle curves adjustment and everything looks great. There is a hint of bronzing at acute reflection angles only. The paper is relatively affordable and I have a bunch of it around after using an Epson for 4 years, so unless HP's premium satin is a whole lot better I may be using it a lot. (Still waiting for HP paper from their free media deal).
