As far as I am aware Thunderbird only has print preview settings. Every print needs to go via that where the settings are displayed. Do you perhaps have the printing tools addon installed? It offers a ctrl+P print option. It also offers the traditional page settings which where removed when the print preview arrangement was implemented.

Thanks much for the quick reply, Matt. You are absolutely right, it's working now just as you described and, no, I have no add-ons. However, on an incoming email, if I go to File, the Print option does reference a Ctrl+P, but clicking on Print, or using the shortcut, I now get the Print Preview page just fine. This is strange, because a bit ago Thunderbird was bypassing this step and sending data to the printer immediately. Just a fluke, perhaps; I'll keep an eye on it.

While I've got you cornered, do you know, offhand, if there is a way to specify the Windows default System Dialog box for printer selection and setup, rather than the one that looks like the one below? I can get there by clicking a hyperlink at the bottom, but would prefer to skip that step if possible. Many thanks! https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-11-17-16-05-22-ed4562.png

1. Windows does not have a default as such any longer so each app provides it's own. 2. The addon I linked to offers such a dialog for setting persistent preferences, including header and footer details that are non user set in the base product. 3. The reality is most of us do not change the basic defaults for the printer each time we print, they are set in the operating system and meet general printing needs most of the time unchanged. The choice of double sided Vs single sided perhaps being the dividing feature.
