I print, I plan the whole day out for shops, I am not one just to go and done one shop and then come home. I want an average of 12-14 if I can so it makes the day more profitable. I purchased a HP8710 and just have the ink refilled at costco, for cheap. I fill the report on paper that way there is NO confusion with which location and for how many cookies. Its all there in black and white. Yes, I might spend more on paper, ink, etc but this is something I add into my shoppers pay, like mileage, upkeep on vehicles, etc.
Also its great reference , when in doubt for the shops requirements, its right there...
