What are the weaknesses of Z3200 in your opinion?
In my opinion (but others milage will of course vary) some pros and cons of the Z3200 are as follows:
1. Ink stability is poor as I found out to my embarrassment with a discerning customer. It is essential to regularly calibrate with the built in spectro and not ignore the prompts to do so. It isn't difficult to do and only requires a few moments of time to load an A4 sheet of the offending media and leave the rest to the printer. (I am preaching to myself as I ignored the prompts to my cost).
2. Under a loupe I have noticed that with PhotoRag Ultrasmooth Z3200 dot patterns are sometimes visible. Ok, I realise this is dot peeping but for the same image on the same paper, my Epson x900s have had no observable dot patterns even with a loupe.
3. Print speed is relatively slow.
2. Paper loading especially roll is a PITA.
5. Star wheel patterns were supposed to be fixed on the Z3200 but on every thicker semi-gloss/pearl type papers I have tried they are still evident although admittedly very feint. Thinner papers such as Ilford Gallerie Pearl seem ok.
There are things to like about the HP though.
1. Even after 5 or so years, the HP still has a strong lead on light fastness according to Wilhelm.
2. Apart from my self inflicted ink stability embarrassment, my Z3200 has been 100% reliable.
3. Great black and white support. I used my Z3200 to produce the 100 or so large individual b&W giclee prints to the London exhibition of the 1960s photographer John 'Hoppy' Hopkins a few summers back with positive feedback. http://gallery.ideageneration.co.uk/blogs/52/view
