At any time from the GreenHopper Planning Board, you can print the issues in a card form. You can access this print action within each box of the column of the Planning Board. All issues associated with that box will be in the print queue. e.g. If you want to print all the issues of your product backlog simply select the 'Overview' mode of your Planning Board then hit the print button of the single box of the column.

The pictures and background colours used for printing are taken from your browser settings. For example, in FireFox you will find these under 'File' > 'Print Setup' > 'Options'
