Photo printers often feature a large LCD screen that can be used to select a picture and, in many cases, to edit the image (for example, removing red-eye). But even printers that don’t have the big LCD screen can be PictBridge compliant. Simply attach the camera to the printer with a USB cable and use the camera itself to select the pictures to be printed and any available options.
My Pixma MP530, for example, a multifunction printer, has no screen for viewing photos but I can still print photos directly from a PictBridge-compatible digital camera. Once connected to the printer, the printer allows some basic choices (such as compensating for backlit photographs), and then I can start printing.
So if you take a lot of photos and like to print them out, make sure the printer you buy is PictBridge-compliant. Look for the logo seen on the right.
