Remove the header and footer from printed pages
Most browsers add a header and footer automatically to every page they print. You can remove these to give your documents a cleaner, more professional look. Each browser has a different way to remove these:
In general, you need to uncheck the option in the browser's print window for the headers and footers.
Save a document as a PDF file
Order Printer uses your browser's print function to print documents. Each browser and operating system handles saving to PDF a little differently.
Google Chrome on Mac OS X or Windows
If you're using the Google Chrome browser, you can save to a PDF directly from the print dialog. Under Destination, click Change... and then select Save as PDF:
Mac OS X
Mac OS X's print dialog will allow you to print to PDF from any browser. In the print dialog box, select PDF on the bottom left and then select Save as PDF...:
For browsers other than Google Chrome on Windows, you can use software like CutePDF to save to PDF from any print dialog. On Windows 10, you can specify that you want to save as PDF in the Print window.
