Hi @chriskim2311 let me know if you need accessibility review from me about this issue, But here is my though,
Visible Label & Description: The "Print this page" button should have a clear, descriptive label, such as its own text or an appropriate aria-label for screen readers. For Keyboard Focus to make sure users can reach the "Print this page" button using the Tab key. The button should show a visible focus state (like a border or color change) when selected. In adding Role and State the button should be correctly marked as a "button" (using the element or ARIA role) and should be in the right state (enabled or disabled).
For Print Button Action Feedback when the "Print this page" button is clicked, let the user know what’s happening. If a new window or print preview opens, use ARIA live regions or an alert to notify users that the print dialog is starting.
