摘要： A print material usage estimation device may comprise a first usage meter to measure a first print material usage associated with print material deposition on a print medium over a specified time period. 5 The print material usage estimation device may further comprise a second usage meter to measure a second print material usage associated with other printer processes over the specified time period. The print material usage estimation device may further comprise a ratio calculator to calculate a ratio between second print material usage and first print material usage over the specified time period. The print 10 material usage estimation device may further comprise an estimator to estimate total print material usage for an instructed print job based on a predetermined first print material usage for the print job and the calculated ratio.
