From Ted Richards …
How I get web pages that don’t print into a format where they will:
Use the ‘snipping tool’ in Windows, select and paste it into Word or PowerPoint or something similar, and print.
On a similar vein, if I want to copy some text and the web page is set not to allow copying of text, I use the snipping tool, select and same as a jpeg, then use the OCR reader https://www.newocr.com/ to convert the picture into text and copy into the document I want it to be in.
