Use and AirPort Express or an AirPort Extreme with a USB port. Connect the printer to the USB port, configure the Airport Extreme/Express to replace your current router. Then your printer should appear in the Printers&Faxes Preference Pane under Bonjour Printers. You may need the latest drivers from HP, but all should be well. Depending on the drivers, you may only be able to print wirelessly, but have to be directly connected for scanning.
