"Worksheet","Does grayscale printing mean only black ink is used?","Evidence status","Your configuration"
"Purpose","A grayscale-looking page does not establish which supplies the printer used. Check the exact model and mode documentation, and keep appearance separate from consumables accounting.","Proposed workflow",""
"Check","Question to record","Decision","Your observation"
"Appearance","Neutral output","Does not reveal supply use",""
"Mode","Named driver option","Read its documented behavior",""
"Accounting","Supplies purchased and useful pages","Include other stated costs",""
"Example","In a hypothetical budget, a household prints 90% monochrome documents but still buys a color set for documented maintenance or mixed jobs. Assigning zero color cost merely because most pages look gray would understate that household’s observed expense. Record the actual purchases instead.","Illustrative; not a measured product result",""
