[sylpheed:32814] How to adjust margins of printed messages - 2.6.0

[John Shane]

Sylpheed 2.6.0

I would like to change the margins of messages printed through
Sylpheed.  I know I can do it using enscript but is there a way to
change them when using the built-in Cairo-based printing facility
(which is easier to use with multiple printers)?

So far I haven't turned up an answer looking through the FAQ's,
manuals and Google references.

Thanks,

John
