Hi Doris. If your printer is Apple compatible you don't need to use a USB stick. If your printer is not Apple compatible you may still get it to print. Example I have an old Brother printer non Apple. But Brother has an app that allows it to print from an iPad. In my case I turn on WiFi and enable Hot Spot. Then "tune" the printer into the WiFi. (Only need to do once). If you buy another printer make sure it is Apple compatible and life will be real easy!
