I found this a powerful tool to save paper and customize how messages
were printed.
I’m disappointed to see it missing after my last Thunderbird update
yesterday.
Can I revert to the previous version of Thunderbird?
You must be referring to version 91.
The workflow for print is now different. “Print” automatically puts
you in print preview.
If you want to select text and print only the selection, that capability
does not yet exist. It is being investigated.
