This is covered in Tech Note #192.

In LaserWriter 5.0 the low level printer driver calls are converted into
corresponding high-level calls.  One of the results is exactly the problem
you described.  The solution given in the Tech Note is as follows (in
Pascal):

	PrDrvrOpen;
	PrCtlCall(iPrDevCtl, lPrDocOpen, 0, 0);
	PrCtlCall(iPrDevCtl, lPrPageOpen, 0, 0);
	{ send data }
	PrCtlCall(iPrDevCtl, lPrPageClose, 0, 0);
	PrCtlCall(iPrDevCtl, lPrDocClose, 0, 0);
	PrDrvrClose;
