The PS models were supposed to have bigger drives and more memory for the Z 3100 too.
True the 24" Z 3100 was delivered in theory with 69ml carts vs the full 130ml carts. The Z 3100 44" was delivered with 130ml carts. No idea what is up there.
They claim it to be that much faster. Exact reasons have not been disclosed.
I think you mean turn it upright, unless you're like me where turning it to stand upright is necessary to pass through a doorway, it is not a good idea as the frame is quite stressed.
My printer assembly directions called for turning the main body of the printer upside down and attaching the legs. Then it called for standing the printer upright. (inverting it).
BTW: the ink cartridge kit was labeled "Red Baron B1K Kit"...(Hmmm...Sprechen Deutsch?)
So far, there is little difference in test images I'm printing from the Z3200 compared to the Z3100. However, compared to the Z3100, there is less noticable star wheel tracking on prints from the Z3200 on gloss photo (Professional High Gloss contract Proofing Paper) and Océ Clear Film. But, if you want to find some tracking, it's there...you just need to look more closely. For my own and my clients' quality criteria, I believe that the Z3200 has eliminated any star wheel tracking that is immediately visible to the naked eye under 'normal' lighting conditions, and therefore it is producing acceptable gloss and film output.
I have never had a problem with reds on the Z3100, so I'll not bother doing any comparisons there.
The Z3100 does a fantastic job of printing on canvas, satin, and matte papers. In fact, I continue to steadily increase the client base of my fine art reproduction and exhibition photograph business, based solely on "word of mouth" referrals.
My suggestion is to stay with HP paper (except for Océ film). The only head crash I've had with the Z3100 was when I tried some canvas samples from another manufacturer, and I'm quite pleased with Pro Canvas, Pro Satin, and Contract Gloss.
Also, for those of you contemplating whether to purchase the 24" or 44"...don't hesitate, go for the 44". You can always run 24" or 18" roll stock of the 44, but you have the option to print larger if a client requires it. Many times I regretted not buying the 44" Z3100. And, get the ps model if your budget allows. (Gigabit network, Postscript, Pantone, larger prints, etc.)
So in conclusion, it looks like HP has done a good job on the new Z3200 in clearing up some of the problems of the Z3100...now, I need to get back to work.
