ISO DPA: Document-type This attribute indicates that the document being passed by the current Print abstract-operation is either a printable document, a font, or a resource.

How resources are managed during the printing process is necessarily dependent on the characteristics of the server and printer implementations. These methods are considered implementation-specific, and shall not be dictated by ISO/IEC 10175. In particular, ISO/IEC 10175 does not require that resources be passed in advance of the documents that use them; i.e., resources may be passed to the server in any order within the job, subject only to the requirement that the resources be present at the server before processing begins on the documents that use them.
