See article in HP: "HP Deskjet, professional series Printers, Laserjet Printers - Microsoft (R) Word, Collate, Reverse print order and ordered Printing are not working properly"
Don't have the URL.
Search with above keywords in HP support. You'll see the several combinations on the application and on the printer driver. Choosing Reverse order or Ordered printing in driver and in appplication has several effects: you get it or you don't.
I always choose Reverse order or Ordered Printing in driver only and forget the application: it works
(for instance, if you choose in Word, Preferences, Print , Reverse Order and also Reverse Order in the driver, the effect is to get Ordered Printing - more or less like -1 x -1 = + 1 )
