The HP driver's media sets work very well, and profiling on top of them gets excellent results. HP's black and gray inks are, unlike Epsons, quite neutral, and this lends itself to extremely aggressive GCR, which is applied behind the scenes. With Grayscale images or even RGB grays the GCR is 100% and they are processed with black and gray inks only. When matte media are selected the matte black and 2 grays are used but also the photo black ink, which being slightly less dense on matter media serves as a dark gray, so it's a quad-tone. Pretty elegant. On the other hand the Z31/3200 are not driven so nicely by some third-party RIPs: gamut is smaller, with less smooth boundaries. The best solution, I've found, is to use a RIP that has incorporated the HP RGB driver; then one has all the productivity of a RIP (nesting, tiling, hotfolders and multiple print queues, foolproof color presets, etc.) plus the superior screening and color output of the RGB driver. Inside the RIP one still must select the media type as in HP's driver. The same approach can be used with some Epson and Canon models--many RIPs now are including RGB drivers.

On the HP Z3100-3200: HP has documents on the inks used with different media presets + the ink limits per media preset for the normal OEM driver. There are also documents which media presets to use for third party media. You can create a custom media preset based on an OEM one and make slight changes on the ink load + drying time etc. and then calibrate the third party paper + make the profile. Non-inkjet papers can be used as well, the Arches falls in that category I guess.

http://groups.yahoo.com/group/Wide_Inkjet_Printers/ has a map in the Files with several docs on the subject.
