A method is disclosed for generating pricing data for managed computer printer services for a user of a fleet of computer printer devices over a contract time period including first selecting between two possible pricing models, pay-per-page with minimums or pay-per-page with a fixed periodic payment. Variable costs comprising the costs of toner cartridges and preventative maintenance are computed for both monochromatic and color printers and these respective variables contribute to determine the total costing of both models. In the fixed periodic model the cost of hardware and a service fee also contribute to the final pricing figure. The toner portion of the variable costs element may be determined on the basis of predictions of page coverage for both mono and color printers, but may also be determined from historical averages resulting from actual measurement of the page coverage of printers in the fleet.
