If the anchor tag already has the URL as text, then will the URL be printed twice?

Like if I've got

  <a href="https://www.google.com/">https://www.google.com/</a>

Will it print like this?

  https://www.google.com (https://www.google.com)

Based on the above, yes.

would recommend printing URLs in a very narrow font so they don't eat up the entire page

That's a pretty common Accessibility best practice for print CSS!

Shouldn't this be an option in the browser print dialog instead?

No

Great argument.

They asked a yes/no question. In the spirit of HN pedantic comments, I answered their question fully.
