When printing certain PDF documents from the website, diagonal lines may appear over various parts of the printed document. This issue typically occurs on laser printers. If you find this affecting you, there are two ways to solve the problem.

When you go to print the PDF document a window should pop up with various options listed on it, before the document is printed. Look for a dropdown box named Print Method and then change the dropdown so that it displays Language Level 1. Now click the print button and see if this fixes the problem.

If this does not work, on the same print window look for an option named Print as image. Click on this so that the option is selected, then finally click the print button. One of these two methods should correct the fault, allowing you to print out your PDF document without diagonal lines.
