Hello scouts,
Welcome to Digicamhelp!
I've actually not had time to try pictbride. I've had an old printer until recently and my new one is pictbridge compatible.
Yes, you must make sure your new printer is pictbridge compatible so it will work with your digital camera.
If I understand your question correctly, you don't need a special adapter. All you have to do is connect the camera to the printer, and you'll be able to edit through your camera menu system and looking at the LCD. Also, some printers come with a built-in LCD screen and you can edit using the printer.
Hope this helps. If not, let us know.
