If your inkjet printer says it’s out of ink, don’t believe it for a second (until the ink goes faint on the page). Most printers lie like a rug, claiming to be out of ink long before they actually are. Epsons are the honest-est, reporting “empty” when down to about 20%, while some Kodaks report empty when only 36% of the ink is gone. Not to mention the problem of multi-cartridge printers claiming to be out when only one color has run dry.
It’s the old “Give away the razor, sell ’em the blades” (Gillette in days of yore) thing, aka the “Give away the camera, sell ’em the film” thing (Polaroid in days of yore). Only razors and cameras didn’t lie about the need to replace consumables like printers do.
Which is one reason why we only use a b/w laser at home, and send out for color prints when needed. Inkjets only look cheap.
