Whatever printout font I define, kmail ignores it.
The print preview always looks the same.

No wait - I found that kmail uses the defined printout font but ONLY for the subject line
on the printout.
More testing shows that this is not only a printing problem. Also the font selected for "message body" is not used on the message body but also only in the mail header display.

I'm using "Fancy Headers", but with other header styles it's worse - the fonts seem to be ignored completely.

Reproducible: Always


Actual Results:  
Currently a printout is too tiny - hard to read.

Expected Results:  
I expect the font to be also used in the body of the message - this is the most important part I want to print.
