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

       /UPPERCASE
       /NOUPPERCASE

    Indicates whether the printer prints both uppercase and lowercase
    letters or only uppercase ones. When you specify the /UPPERCASE
    qualifier, all letters are translated to uppercase.

    The /[NO]UPPERCASE and /[NO]LOWERCASE qualifiers are
    complementary; that is, the /UPPERCASE qualifier is equivalent
    to the /NOLOWERCASE qualifier, and the /NOUPPERCASE qualifier is
    equivalent to the /LOWERCASE qualifier.
