How come the Kakuro puzzles print out as an empty box?
Browsers don’t let us automatically print the background of the Kakuro puzzle, so you can “Save PDF” and then print or follow the steps below: If you’re using a version of Internet Explorer, open the “Tools” menu in Internet Explorer, select “Internet Options”, switch to the “Advanced” tab and enable “Print background colors and images” in the “Printing” section. If you’re using Firefox select “File” found in the top left corner of the browser, scroll down to “Page Setup”, and enable the Options checkbox “Print Background (colors & images)”.
