In cups I have the uri set to the above.
Bus 002 Device 082: ID 05ad:0fba Y.C. Cable U.S.A., Inc.
The driver that worked for the parallel to usb was the HP LaserJet 4050
Foomatic/hpijs.hpijs 18.104.22.168 - HPLP 2.8.2 [en].
Device: gives me a drop down list with the first one being AppSocket/HP
JetDirect - which Im assuming is the right one to use.
