TabbedTextOut(): What am I doing wrong?

Environment: VC 1.52 WfW 3.11

In my doc I load a CStringList with strings preceded by a number of 
"\t" tabs to indent appropriately and attempt to draw the text to 
the printer DC in my view in OnPrint() like this

	C84inchDoc* pDoc = GetDocument();
	ASSERT_VALID(pDoc);
	CFont* pOldFont = pDC->SelectObject(&m_font);//12 pt Times N R
	int lineheight = GetCharHeight(pDC);//returns tmHeight +
                                             tmExternalLeading
	
	CString str;
	for( POSITION pos = 
          pDoc->m_output.GetHeadPosition(); pos != NULL; )
	{
		str =  pDoc->m_output.GetNext(pos);
		pDC->TabbedTextOut(0, m_nPos,
					   str,str.GetLength(),0,NULL,0);
		m_nPos -= lineheight;
	}
	
	m_nPos = 0;
	pDC->SelectObject(pOldFont);


Mapping mode is LOENGLISH.  This works great for all the printers I 
tried it on in Print Preview, but while actually printing on a few 
printers it clips off a seemingly random portion of each text line.  
It works on all the laser printers I tried, doesn't work on an ENCAD 
plotter or a Panasonic dot matrix.  Both clip the text in the same 
way.  If I take out the \t in the strings, everything is cool.  I 
tried passing a tab position array with same results.  This must be 
something really embarassing and stupid, so be gentle.
