/sys$common/syshlp/helplib.hlb SET, PRINTER, Qualifiers, /TRUNCATE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /TRUNCATE (default)
       /NOTRUNCATE

    Controls whether the printer truncates data exceeding the value
    specified by the /WIDTH qualifier. Note that the /TRUNCATE and
    /WRAP qualifiers are incompatible.
