Upgrade to Yosemite and HP MFP M27nw fax doesn't install

I just upgrade my late 2013 Mac Pro to Yosemite. My HP MFP M27nw all-in-one had been installed both as a printer and a fax under Mavericks. The fax didn't work after upgrading to Yosemite so I deleted the printers and reinstalled, both using the Apple drivers and downloading from the HP site. The printer installs without any problem. However the fax doesn't install.

I tried manually installing but the "Use" pull down menu only shows:

no fax option is available.

So how do I install the fax printer?
