You can print one article at a time using the Print Friendly toolbar above each article.
Open the article.
If your article has expandable headers, then expand those containing article text you want to print. If you are not interested in particular sections, you can keep those collapsed.
Find the Print Friendly toolbar above the article.
Once you click any of these tools, you will see a print friendly window pop-up:
Print: Displays the default Print window in which you can choose your printer and printer options.
PDF: Displays a Download to PDF window. Click the Download button. You'll find your downloaded PDF file in your default Downloads folder.
Email: Launches your default Email client with the first few lines of the article and a link to open it in the browser.
