Scope

This Document defines the auxilliary objects which are common to all printer device classes. The objects
in this category are PrintForm. PrintField, PrintMedia, PrintImage, PrintResolution,
PrinterReadMediaType, PrinterWriteMediaType Extent and PrintLayOut objects.
Since data for the printer is specified through forms, an automation object is defined to represent this
form. This object cannot be instantiated directly. It is returned as a result of method or property invocation
on a Printer Control. PrintField is defined in similar fashion as an automation object to present fields
within forms. A printer can support multiple forms and a form contains multiple fields. A dictionary object
is used to give access to the forms and fields. Since the dictionary supports enumeration interface, it is
possible to either enumerate over all objects in the dictionary or access individual objects through a string
key, which is typically the Form or Field name.
The properties of the media supported by the printer are exposed through an automation object called
XFSPrintMedia. The MediaList on print controls returns the list of supported media objects.
The XFSPrintImage object is used for accessing the ImageData that is returned as a result of ReadImage
call in Document and Receipt Printers.
The XFSPrintResolution, XFSPrinterReadMediaType, XFSPrinterWriteMediaType objects are used
represent resolution, Read/write media types capabilities in any of the four printer device classes.
The XFSPrintLayout object is used define the layout of form on the physical media while printing.
The XFSExtent object specifies the dimension of media in the GetMediaExtents method.
