Writer and PDFCREATOR

A document written with Symbol font in Libreoffice Writer is not printed properly with PDFCreator 2.1. The same document is printed correctly from Microsoft Word. What needs to change in settings in order to have proper printing font Symbol?
thanks

why not use the PDF export inside to LibreOffice?

Because it is not possible to insert a password
Thank you

For insert Password: Menu> Export as PDF, in the PDF Option select Security table and click SetPassord… is This? LIbreOffice 4.x - 5.x
