No. Look at QDBegin/EndCGContext

They are not the same. The full story is here:

onSetDocumentFormatGeneration

<<<<<
On return, a reference to the current graphics context. The graphics context
returned is the one last set by a call to the function
PMSessionSetDocumentFormatGeneration or the default (QuickDraw) if there was
no call to the function. This reference must be typecast to an appropriate
structure (such as a grafPtr) by the caller.

You should call this function for each page you draw for a print job. After
each call to the function PMSessionBeginPage your application should call
PMSessionGetGraphicsContext to obtain the current graphics context. If that
context is a QuickDraw context, then set the drawing port to this port by
calling the QuickDraw SetPort function. See the discussion of the function
PMSessionBeginPage for more information.

In Mac OS 8 and 9 applications are limited to a QuickDraw context, so
PMSessionGetGraphicsContext returns a grafPtr. In Mac OS X, the graphics
context returned to you is the one last set by a call to the function
PMSessionSetDocumentFormatGeneration.
