Yeah, you're right. It seems as if both user stylesheets are not
respected when printing (at least with mail; I didn't test with the

Yes, but it's only a kind of elaborate workaround I found.

When I manipulate the print preview with the DOM Inspector, my
manipulations are printed. So you could do this:
Require the print preview to be used; overlay it with your code.
The print preview contains - as you said - a <browser> element that will
contain the document to be printed. You have access to its #document via
its contentDocument property. You then could add a custom
<link rel="stylesheet" href="your stylesheet">
to the document's <head> element...
Feel free to correct my English. :)
