You should try to preview the job before printing.
The problem look similar to one that we could solve only by issuing:

#INCLUDE COSTWORD.H 
LOCAL ln

WITH oword
	FOR ln = 1 TO 2 &&yes, twice!	
		.ActiveDocument.PrintPreview
		.ActiveDocument.ClosePrintPreview
		.Selection.HomeKey(wdStory) &&first page
	ENDFOR
ENDWITH
