Onebooth allows you to print via Apple's proprietary printing solution AirPrint. Most new consumer printers like the Canon SELPHY support AirPrint. Apple provides a list where you can double-check if your printer is compatible.
Tip: Some companies may state that their device is generally iPad compatible. Those printers usually require an additional app from the manufacturer and therefore won't work with Onebooth.
