Save to PDF now - with no preview by jscher2000

Three ways to print

Best for pages that you know will print correctly from past experience, since there's no preview.

Toolbar button

Click the button to open the setup panel. Print without customizing, or set your own margins, headers/footers, etc. Note: for quicker access, pin the button to the main part of the toolbar using the steps in Manage your extensions using the extensions button in the toolbar.

Or Shift+click the button to immediately generate the PDF. If you prefer to make a regular click do this, look for the "When I click the toolbar button" setting on the setup panel, and use Save Changes and Generate PDF to save it.

Right-click context menu

Regular click the "Save to PDF now" menu item to immediately generate the PDF. Shift+click it to drop the setup panel and customize your margins, header/footers, etc. (Note: drop-down doesn't appear in popup windows that do not have a regular toolbar.)

If you want to reduce menu clutter, you can remove this item. Right-click the toolbar button and uncheck "Show context menu item."

Keyboard shortcut

By default, Shift+Alt+P will immediately generate the PDF. Since this is a bit awkward, you can customize the keyboard shortcut using the steps in this support article: Manage extension shortcuts in Firefox.
