With PDFCreator you can adjust the values appearing in the file properties of your converted document.
You can set templates for Title, Author, Subject and Keywords.
You can use tokens here. For more information, please visit the Tokens section
Added tokens (from the right list) will change their value according to the actual print job.
E.g. <PrintJobName> is the token for the original title from the print job and the default value for the title template.
The same applies to <PrintJobAuthor> for the author.
