Once you transfer content to your custom document, you can edit the text and graphics and even resize and delete them. Then print exactly what you see on screen. HP Smart Web Printing will also save your custom document as an Adobe PDF file. HP Smart Web Printing automatically scales web page output to fit the width of your paper. This helps ensure that your print copy contains all the information you see onscreen. Text and images will remain intact.
