And there's a possibility that, though the value is the same, that the
content isn't.

It wouldn't surprise me to find the HDC being released back to Windows
when the next printer is indexed, and Windows then generating a new DC
in the same place for the new handle.

The whole concept of using the Printer object is not one I've tried - my
printer code is all written using the underlying API, with
DocumentProperties() and OpenPrinter() and ResetDC() and the like. I
suspect that the Printer object is fine for simple use (printing
reports, say), but may be a little limited for advanced usage.
