Epson Stylus C59
Intellidge™ ink cartridges contain sophisticated circuitry that maintains an accurate record of how much ink has been used and the amount remaining. Instead of running out of ink half–way through a print, the printer driver checks on the amount of ink in each cartridge then displays a warning if one or more cartridges are running low.
Since each Intellidge™ ink cartridge tracks its own ink levels and maintains that information even when unplugged from the printer, it's the best possible system for using full cartridges for continuous large print jobs whilst partly used cartridges can be used for other smaller jobs – maximum ink usage, maximum benefits.
