Returns a pattern with a regex_string field set to " [a-zA-Z0-9]|[!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~]| ", a combination of alphanumeric and punctuation characters and a space. This pattern is useful for matching these so-called 'printing' characters in the target string.

Example: String contains printing characters

<pattern  pattern.<one_or_more pattern.printing /> />.
<is_type_for <join char.tab "Abc " char.carriage_return char.newline /> />

true

Example: Does not contain printing characters

<pattern pattern.<one_or_more pattern.printing /> />.
<is_type_for <join char.tab char.formfeed char.carriage_return char.newline /> />

false
