The enhanced metafile format provides a format into which documents are readily converted and which occupies a minimal amount of storage space. Each spooled print job is asynchronously printed relative to a program that requested the print job. Such spooled print jobs are de-spooled in a background processor mode. An operating system provides the resources for converting a print job into enhanced metafile format and spooling the print job in the enhanced metafile format.Other References
