When I access this site and try to print it, I see nothing but a blank page in the print dialog box. However, if I go to File > Export as PDF and then print the PDF, all is well. This has sometimes happened with other sites as well. Any thoughts?

I looked at the source code for that page and except for an HTML file header and footer it is entirely javascript, which your browser interprets/renders into an image that is expressed in PDF for display on the screen. When you print the file there is no printable image because there is no interpreter for the javascript, but when you choose Print to PDF, it grabs the PDF display image the browser, or any other application, generated to create the screen display and sends that to the printer.

Very informative! Is there anything that I can do to change this?

in a word NO, there is nothing you can to do change this. To change it would require

• the site developer to completely rewrite the code for the page or,
• a thorough and dramatic redesign and rewrite of MacOS eliminating features and functionalities that have been an Apple hallmark feature since the mid 1980's or,
• possibly switching to a Windows based PC (I haven't touched a PC in this century so I don't know if that would work or not).

Thanks. It's no big deal since I can work around it easily.
