Library /sys$common/syshlp/mailhelp.hlb PRINT, Qualifiers, /BURST  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /BURST=keyword
       /NOBURST

    Controls whether Mail inserts a burst page before printing a
    message. The /BURST qualifier can take either of two keywords:
    ALL or ONE. The ALL keyword indicates that each file in the job
    is to be preceded by a burst page and flag page. The ONE keyword
    indicates that a burst page applies only to the first copy of the
    first file in the job.
