I received my Z3100 printer (44inch) yesterday.
I have installed the driver software and also updated the printer firmware to version 5.0.2
When I open the HP Printer Utility> HP Color Center there are only two option available- Calibrate your Display and HP Printing Knowledge Center.
The options for creating, ICC Profile, Install ICC profile and Manage Missing Paper are missing.
I have uninstalled and re-installed the software twice
I have also downloaded the latest HP Utility version 2.8.0 from the HP web site but this has not solved the problem either
Attached screen shots explain the situation more fully
