<pre><b>INT 17 - PRINTER - WRITE CHARACTER</b>

	AH = 00h
	AL = character to write
	DX = printer number (00h-02h)
Return: AH = printer status (see <a href=../../it/31/6.html>#00631</a>)
Note:	Under PhysTechSoft's PTS ROM-DOS the parallel port can also be
	  accessed as COM5.
BUGS:	Some print spoolers trash the BX register on return.
	Some original IBM BIOSes set more than one printer status bits at
	  a time, while only one of them is correct.
