Maybe your printer has an internal memory buffer.  I suspect most do.  I 
think that the print queue reflects what has been sent to the printer, 
not what has actually been printed on paper.  My old HP Deskjet 540C 
acts this way.  Try unplugging the printer. Just turning it off probably 
won't work.
