RTF is a cross-platform format for storing labeled text documents, created jointly by Microsoft and Adobe, as meta-tags for the format Word in 1982. Adobe has in 1985 continued to develop the format and created a language PostScript. The basis is a simple text format, control sequences which are not macros that are available for change, and teams with a fixed behavior.
Open XML Paper Specification (also referred to as OpenXPS) is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). It is an XML-based (more precisely XAML-based) specification, based on a new print path (print processing data representation and data flow) and a color-managed vector-based document format that supports device independence and resolution independence.
