You can get nearly all the functionality of the HP ToolboxFX simply by browsing to the printer's IP address in your browser.
Double-click on the printer Under "Devices and Printers" and then on "Customize your printer" - then "Ports" - just scroll down the list. Enter that IP address in your browser.
Everything is there except for the "print cleaning page" function.
BTW, try using Windows to search for an updated driver
- it's likely available now (mine was).
