I have an Hp 450c potter. I have a draft medium and fine print setting on the unit, however if I set it up to print fast (draft) it will still print in fine. After I print 4 or more sheets it will go into the draft mode, It will print a few sheets that way than it will go back to normal printing...can anyone shine some lights on this?
