If you’ve ever wanted to capture the entire contents of a Topic Discussion from a Discourse site, such as LinuxCommunity.io or ubuntu.discourse.com, there is a simple way which was recently pointed out to me on the Ubuntu site here.
Using CTLP will cause the browser to send a signal to “transform” the full set of posting in the topic’s discussion as a single HTML page, along with the prompt to print, where the option to select “Save as PDF” is available.
