Printing mail is simple.  Enter l (mh-print-msg) (for
line printer or lpr).  The message is formatted with mhl
and printed with the lpr command.  You can print all the messages
in a sequence by specifying a prefix argument, in which case you are
prompted for the name of the sequence (as in C-u l frombob RET).
