I got back in town today, and have been slogging through the zillion messages I missed while gone. The on-going discussion over the Epson cartridges has been interesting. At the risk of heating it up again, here's how I understand what's going on.
The Epson cartridges have a small circuit board in the ink cartridge that has a few bytes of RAM. The RAM contains an estimate of the amount of ink remaining in the cartridge. When a cartridge is inserted into the printer, the RAM is read into the printer. As the cartridge is used, the printer "guess"timates how much ink has been squirted, and periodically writes a new estimate of the remaining ink to the RAM in the cartridge. | The next meeting of the Louisville Computer Society will | be January 28.
