Legacy print button navigates to non-existent print.html, causing repeated print dialogs and broken print usage when navigated

Print Button Glitch

Summary

The current Print button links to print.html (which doesn't exists) which causes the browser print dialog to be re-triggered repeatedly when users navigate back and forth, both on web and mobile browsers.

Expected Behavior

• Clicking Print opens the browser print dialog (window.print())
• No page navigation occurs
• Canceling print or navigating back does not re-trigger printing

Actual Behavior

• Clicking Print navigates to /print.html
• Print dialog is triggered
• Navigating back or switching tabs triggers print again
• This creates a UI glitch

Impact

This is a UI glitch that disrupts normal reading flow and ruins user experience, especially on mobile devices where back navigation is common.

Edit: print.html does exist, since this is a special page generated by mdBook
