I never print the Listener crossword direct from the site. My routine might look time-consuming but it's very easy and gives me total control over all aspects of the puzzle's appearance, size etc. I highlight, paste and copy the title into a Word document; I then highlight, paste and copy everything else except the grid into the Word document; then I right click over the grid and chose "save image as..", saving it to my desktop; lastly I insert the image in the document using Word's "insert/picture" command. Once the image is in the document it's possible to size it as you want, either by the method described by Ruthrobin, or by right-clicking on the border of the image, choosing 'size' or 'format image', and specifying the exact dimensions required.
By adjusting font size, margins etc I can make sure the puzzle never fills more than 2 pages, and I can keep it on the computer for future reference.
