+@item set print raw-values on
+Print values in raw form, without applying the pretty
+printers for the value.
+
+@item set print raw-values off
+Print values in pretty-printed form, if there is a pretty-printer
+for the value (@pxref{Pretty Printing}),
+otherwise print the value in raw form.
+
+The default setting is ``off''.
+
+@item show print raw-values
+Show whether to print values in raw form.
+
@item set print sevenbit-strings on
@cindex eight-bit characters in strings
@cindex octal escapes in strings
Note that for @code{bar} the entire printer can be disabled,
as can each individual subprinter.
+Printing values and frame arguments is done by default using
+the enabled pretty printers.
+
+The print option @code{-raw-values} and @value{GDBN} setting
+@code{set print raw-values} (@pxref{set print raw-values}) can be
+used to print values without applying the enabled pretty printers.
+
+Similarly, the backtrace option @code{-raw-frame-arguments} and
+@value{GDBN} setting @code{set print raw-frame-arguments}
+(@pxref{set print raw-frame-arguments}) can be used to ignore the
+enabled pretty printers when printing frame argument values.
