## Discussion

A string identifying the intended output device or production condition in a human- or machine-readable form. This key is required. The value of this key must be a <doc://com.apple.documentation/documentation/CoreFoundation/CFString> object. For best results, the string should be restricted to characters in the ASCII character set.
