All functions are working for me on ubuntu 13.10 with the HP Officejet Pro 8600 plus.
All over wireless network.
I did have to install HPLIP Toolbox to get the multi-page scan working over wireless. Setup the printer with fax in the HPLIP toolbox.
For the memory card you have to use Places > Connect to Server > smb://xxx.xxx.xxx.xxx ip address of printer. Use the user / password of the admin user on the printer.
