In addition to what Teddy says: -- see another 2500CP owner who recently replaced it with a Z3100: http://www.dpandi.com/newsreviews/reviews/z3100jd (note that he's a digital artist, but there are some overlaps since he's also a PSP) -- if you have a Z3100, you can also buy the HP EFI Designer Edition 5.1XL RIP (with PostScript). It's product # Q6643D. I don't have it, so can't speak to its efficacy. Or, you can get the Z GP version that's already PostScript enabled and was just announced. -- All the Z3100s are 12 inks (one is the Gloss Enhancer); it's the Z2100 that has 8 inks (and no Gloss Enhancer). Each Z model comes in 2 sizes; a bit confusing to some people.
Good luck. Harald Johnson author, "Mastering Digital Printing, Second Edition" DP&I.com (http://www.dpandi.com) digital printing and imaging consultant ************************************** See what's free at http://www.aol.com.
