A small subset of Macintosh applications require that PrOpenPage()
set the current port to the printing port...
pascal void PrOpenPage(pPrPort,rPageFrame)
TPPrPort pPrPort;
TPRect rPageFrame;
{
SetPort(pPrPort); /* <<-- Some applications need this. */
/*
(Other printer specific
code which is appropriate for starting the page.)
*/
}
Is this in the specifications for the routine, or is somebody taking
advantage of an undocumented feature?

I would have suspected that the coder of the application got too
lazy to do their own SetPort, it worked on Apple's printer drivers,
so they were never called to account for it.
However, MacApp seems to assume that PrOpenPage leaves the port
set as the current GrafPort, so it would appear that this is
a hidden specification.
