I've passed this along, but I don't expect this to be possible for the short term.  The problem is that two different print dialogs and print engines are used depending upon whether the message to be printed is plain text or is html text.  Now if you have messages selected from both of those groups, it becomes problematic.

Hi,

I would like to suggest something:

Trying to print multiple messages at once today, I had to acknowledge printing for each individual message, which was a little bit, well, boring. Maybe it could be possible that when several messages are marked in a folder window, CTRL+P will just print them all?

Thanks.
