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.

I have another client using Thunderbird and a Brother printer. Same problem. The problem seems to be that TB does not find the Brother printer. TB should have a way to set up a printer for its use. There does not seem to be a way to do that. That is strange

The Brother printer works on all other applications just fine. It is simply that TB does not enroll the installed Brother printer. Since it is not seen as installed by TB, there is nothing to set.

Brother says this is not their problem but Thunderbird's

I sure wish someone would solve this. I am facing my clients either stopping using TB or buy a new printer

I need to make it clear that these are Windows 7 machines.
