Clicking on this button, which has a picture of an Apple LaserWriter on it, will bring you to the regular HyperCard "Print Report..." dialog, where you can specify how you want each field printed, and so on. For more information on this you may want to consult a HyperCard manual, but the controls are rather intuitive. Holding down the option key and pressing this button will allow you to print the entire stack as card pictures, and holding down the command key and pressing this button will allow you to print the current card's picture.
