Welcome to the HP User Community.
It is quite likely this printer requires a Landline phone connection to operate the Fax component on your printer.
Other connection methods might not work as hoped.
Reminder: The phone cable should be a "two-wire" as opposed to a "regular" 4-wire. Two-wire phone cables are available in most office supply or on-line merchants.
