Like all PowerShot digital cameras, these newest additions to the A-series work seamlessly with Canon’s petite SELPHY Compact Photo Printers – an essential PowerShot accessory. Consumers simply connect their PowerShot digital camera to a SELPHY printer – such as the SELPHY CP510 and CP710 models. Press the lighted Print/Share button, and within seconds , images emerge. Presto! It is that simple. Canon’s SELPHY Compact Photo Printers are PictBridge compatible. They work with PictBridge enabled digital cameras and offer excellent image quality and ease-of-use, especially when paired with a Canon digital camera. At 28 cents-per-print , printing photos directly from a digital camera is both easy and affordable.
