5 Appendix A: Product Behavior

The information in this specification is applicable to the following Microsoft products or supplemental software. References to product versions include released service packs.

  • Windows NT 4.0 operating system Service Pack 2 (SP2)

  • Windows 2000 operating system

  • Windows XP operating system

  • Windows Server 2003 operating system

  • Windows Vista operating system

  • Windows Server 2008 operating system

  • Windows 7 operating system

  • Windows Server 2008 R2 operating system

  • Windows 8 operating system

  • Windows Server 2012 operating system

  • Windows 8.1 operating system

  • Windows Server 2012 R2 operating system

  • Windows 10 operating system

  • Windows Server 2016 operating system

Exceptions, if any, are noted below. If a service pack or Quick Fix Engineering (QFE) number appears with the product version, behavior changed in that service pack or QFE. The new behavior also applies to subsequent service packs of the product unless otherwise specified. If a product edition appears with the product version, behavior is different in that product edition.

Unless otherwise specified, any statement of optional behavior in this specification that is prescribed using the terms "SHOULD" or "SHOULD NOT" implies product behavior in accordance with the SHOULD or SHOULD NOT prescription. Unless otherwise specified, the term "MAY" implies that the product does not follow the prescription.

<1> Section 1.3.1: When a Windows application needs to print, it performs the following operations:

  1. First, the application creates a printer device context specifying the target printer.

  2. The application then calls Windows graphics device interface (GDI) methods such as DrawLine to pass drawing instructions to the GDI graphics engine.

  3. The GDI graphics engine accumulates the drawing instructions into an EMFSPOOL file.

  4. The spool file is sent to the Windows print spooler. One of the spool file formats accepted by the Windows print spooler is the EMFSPOOL.

  5. The Windows print spooler interprets the EMFSPOOL, possibly also inserting page layout information and job control instructions into the data stream.

  6. The spooler then sends the data stream to the serial, parallel, or network port driver associated with the target printer's I/O port.

<2> Section 1.4: EMF evolved from Windows metafile format (WMF) [MS-WMF].

<3> Section 1.5: The EMF spool format was defined and intended for use as the spool file format for Windows operating systems.

<4> Section 2.1.1:  The following table shows support for EMFSPOOL records by Windows version.
