IF using Verizon cell as hot spot it is possible they will bill you for all the data that runs through the phone.. EVEN if it is just returning to your printer.
Not sure about other hot spots... When I am using a hot spot my configuration is like this
Printer to/from via USB PC to/from hotspot and internet.
Let me see now if this works.
