Gets a Graphics object that will draw to the next page.
The page is sent to the printer when the graphics
object is disposed. This graphics object will also implement
the PrintGraphics interface.

Ends this print job once it is no longer referenced.
See Also: Deprecated: The finalize
method has been deprecated. Subclasses that override finalize
in order to perform cleanup should be modified to use alternative cleanup mechanisms and to remove the overriding finalize
method. When overriding the finalize
method, its implementation must explicitly ensure that super.finalize()
is invoked as described in Object.finalize
. See the specification for Object.finalize()
for further information about migration options.
