18.104.22.168.1 Printer Escaping
The variable *print-escape* controls whether the Lisp printer
tries to produce notations such as escape characters and package prefixes.
The variable *print-readably* can be used to override
many of the individual aspects controlled by the other
printer control variables when program-readable output
is especially important.
One of the many effects of making the value of *print-readably* be true
is that the Lisp printer behaves as if *print-escape* were also true.
For notational convenience, we say that
if the value of either *print-readably* or *print-escape* is true,
then printer escaping is "enabled";
and we say that
if the values of both *print-readably* and *print-escape* are false,
then printer escaping is "disabled".
