If your digital camera uses a memory card to store photos, you can connect the
camera to the printer to print your photos.
CAUTION: Attempting to remove a memory card while it is being accessed can
damage files on the card. You can safely remove a card only when the photo light
is not blinking. Also, never insert more than one memory card at a time as this can
also damage files on the memory cards.
NOTE: The printer does not support encrypted memory cards.
