Hello

Of course, this is not the expected answer.

For information purposes, since Thunderbird 102. Printing using the system dialog without preview now supported; Set print.prefer_system_dialog to true.

Config editor. Enter a search term print.prefer_system_dialog You can double-click on the preference to set the value to true

There is no entry "Set print.prefer_system_dialog" to change. As I said, there is nothing in the config pretaining to printer of any kind. It looks like there is no printer recognized by TB.

Hello

For my part, i don't know what else to tell you.

Reset Thunderbird printer settings.

For example Firefox https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox It's the same action, Reset Firefox printer settings.

Configuration editor for Thunderbird https://support.mozilla.org/en-US/kb/config-editor Enter a search term print.prefer_system_dialog You can double-click on the preference to set the value to true

There are no printer settings to reset. I suspect the only way to solve this is to re-install TB altogether. I've never done that it sounds ominus. I sure would like to find an easier way.

Would someone else like to try to help????

The solution offered was not possible. The solution turned out to be simple. Re-install TB. I did NOT uninstall TB first. The Re-install evidently corrected the problem.

This problem continues. I have uninstalled and re-installed the printer I have re-installed TB TB does not recognize the printer that is attached and is working for all other applications. TB does not have any entry for a printer of any kind As a work-around, I have saved the email as an html file. Then opened it in a browser and printed it. I have spent many hours on this. My conclusion is that TB for some reason does not see the printer - brother dcw L2550dw This is a Windows 7 system Since the printer works on all other applications, I have to conclude the problem is with TB.
