(Last Updated 02 June 2006) MIME media type name : Application MIME subtype name : Vendor Tree - vnd.cups-ppd Required parameters : None Optional parameters : None Encoding considerations : 8bit This media type may require encoding on transports not capable of handling 8 bit text. Security considerations : PPD files contain printer-specific commands which could cause incorrect printing behavior. See section 4.5.2 of RFC 2046 for examples. The base PPD specification provides a file inclusion facility which is a potential security hole; CUPS does not support it for that reason. Interoperability considerations : The PPD specification requires all applications to support CR, LF, and CR LF line endings, and has a maximum line length of 255 characters, so this file format is extremely portable across platforms. CUPS also supports PPD files compressed using gzip (RFC 1952), which is also cross-platform.
