An array of free-form strings specifying the types of paper that are currently available on the Printer. Each string should be expressed in the form specified by ISO/IEC 10175 Document Printing Application (DPA) which is also summarized in Appendix C of RFC 1759 (Printer MIB). Examples of valid strings are \"iso-a4-colored\" and \"na-10x14-envelope\". By definition a paper size that is available and listed in PaperTypesAvailable should also appear in the PaperSizesSupported property.
