File▸Print menu items enable you to preview or print a hard copy of the files displayed within the file comparison window.
Optimizing printed pages
For best results, use the File▸Print▸Page Setup… menu item to set the page orientation to Landscape before printing.
Merge attempts to use the same colours and fonts in printouts that you see on the screen. If you are printing to a black and white printer, colours will usually (depending on your printer and printer driver) be converted to grey-scales. Some colours that work well on screen may be too faint to read when printed in this way.
Printer drivers vary a great deal in speed and quality. If the printed output generated by Merge looks worse on one printer than on another, you may need to download and install updated printer drivers from the printer’s manufacturer.
