Default font size for printing is too big

Default font size for printing is too big

A recent issue in printing e mails is that the default font size is huge. This happens in both Edge and Firefox. In order to get what I would call a "normal" printout of an e mail it is necessary to go into the printer preferences / options and set the scale to 75%, otherwise a short e mail with signature and logos etc printed at 100% can take 3 or 4 pages.

The annoying thing is that it is necessary to do this each time a printout is to be made as a change in scale only applies to that particular printout.

Any help welcome.
Thanks
