Is it possible to print the sites which use the web fonts, or make PDF files of them?

Yes, it is. However, the Web fonts are designed to be displayed on browsers, and outputting and making PDF files of the sites which use these fonts depend on the functions and specifications of each browser. For this reason, we cannot guarantee the output results. When the print font does not match the displayed font, the default font of the browser may be substituted for print. Please check the font using other browsers and versions.
