Why do you need this printer?
What application does it for?
I had one and didn't like it very much.
It is fast.
There are some bulk ink you could buy online, won't be a huge problem even I used OEM ink with it.
The printhead is cheap and will least around half a year for my "everyday" printing workload.
You can use the onboard i1 to measure the target chart and export the measurement, then reload it in to i1Profiler.
The reasons I don't like this printer are:
I can't use thick paper with this thing, such as Hahnemuhle PhotoRag 308
The paper loading is just a mess
If you are using Windows OS, the driver is not working properly, you better have a RIP with it. I used to use Wasatch with my Z6100. But that means you will have to operate a "RIP"
This printer is just way too big. I can't agree more that someone said this before: look at the Japanese design, Epson and Canon, they are both 60" or above, but their enclosure design are just way better than the HP's.
