An application I'm working on permits the user to perform a screendump
to the printer.  However, it only works on an ImageWriter.  This didn't
surprise me, since Apple's FKEY #4 doesn't work on the LaserWriter either,
and I presume we were both printing the same way - calling PrCtlCall with
the parameters that would cause a screen dump.

How can I screendump to the LW, then (in a way that would be compatible
with the IW as well)?

Would something like this work?  Open a printing port, and then do a 
copybits from the screen's bitmap to the printing port's bitmap?

Any help, hints, and/or sample code (preferably LSC) would be greatly
appreciated.
