(a)    Effective  at  the  beginning  of  its  first  quarter  of  fiscal  year  2017,  HP
          implemented  an  organizational  change  to  align  its  business  unit                
          financial  reporting  more  closely  with  its  current  business  structure.    
          The  organizational  change  resulted  in  transfer  of  a  portion  of  LaserJet
          printers  from  commercial  to  consumer  within  the  Printing  segment.  HP      
          reflected  this  change  to  its  business  unit  information  in  prior                
          reporting  periods  on  an  as-if  basis  which  resulted  in  reclassification  
          of  revenues  between  the  commercial  and  consumer  business  units  of            
          Printing.  The  reporting  change  had  no  impact  to  previously  reported        
          segment  net  revenue,  consolidated  net  revenue,  earnings  from  continuing
          operations,  net  earnings  or  net  earnings  per  share.
