Cost-per-Print Methodology:
Cost-per-Print of four test documents
HP Business Inkjet 1200 vs. Canon i865
Determine Ink Cartridge Yields the average number of prints-per-cartridge for each cartridge
Test files printed continuously, HP-supplied and SpencerLab Printer Test Suite
Black Text, Dignissimas2 Mixed Text & Graphics, Erolm Msupi News Letter, SpencerLab LC Newsletter PowerPoint Slide, SpencerLab Boise 5a
Cartridges judged to be at end-of-life at the earlier of an Ink Out signal on the control panel or when test prints show visible defects attributable to ink supply
HP BIJ 1200: Ink Out signal provided on printer control panel Canon i865: Ink Out signal provided on printer control panel
Testing is repeated over multiple cartridges to assure consistency
Calculate ink component cost-per-print
Divide each cartridge cost by the corresponding cartridge yield (average prints-per-cartridge)
Calculate other user-replaceable component pro-rata costs
HP BIJ 1200 contains user-replaceab le printheads; therefore, include printhead cost in total Cost-per-Print Although the Canon i865 printhead and waste ink tank can b e replaced, neither has a scheduled life nor should they b e replaced under typical usage; therefore, do not include in total Cost-per-Print
Sum these component costs to obtain total Cost-per-Print for the test document
