A:Answer Hi, Joey. You would need a power inverter to power the printer in your car. Then, you can can print from your smartphone. We recommend that you use WiFi Direct. Wireless Direct (WiFi Direct) allows you to directly connect to a printer from a mobile device or computer without the need for internet access or a wireless network. You would connect to the printer’s wireless direct signal just like you would connect to a wireless network. The printer would have a unique name in your wireless connections, i.e. Direct-04-Printer.
