If you want to calculate the true cost-per-page for your LaserPrinter, or other
printer, you should consider the following factors: cost of paper, cost of
toner cartridges, electrical power consumption, depreciation, and labor costs.
However, for the simplest cost-per-page analysis, divide toner cartridge cost
by the number of copies.
Example
-------
$100.00 (toner cartridge) / 4,000 (copies) = $.025 per copy
If the cost of paper is included in the calculation, the equation is: Cost
of toner cartridge plus the cost of paper divided by the number of copies.
Example
--------
$100.00 (toner cartridge) + $20.00 (paper) / 4,000 (copies) = $.03 per copy
(NOTE: The number of copies printed per toner cartridge listed here (4,000) is
an estimate and varies depending on the print density of the documents.)
