The cost of a ream of paper is not the only cost you should consider: you should also think about the cost of toner (see Printing in Color) and the cost of the printer (electricity, maintenance, and depreciation). Using poor quality paper can result in more costly maintenance (see Runnability & Jamming). When you use a standard quality paper instead of Navigator paper, you should also consider the impact of time lost solving printing jams (it can take up to 3 minutes per paper jam).

Not to mention the frustration caused by jams or the loss of productivity: imagine leaving a printer to print for a half-hour job and having it jam after five minutes…
