Digital BW, The Print

Apparantly most recent model Epson printers use ink cartridges with a 
pcb 'chip' to tabulate remaining ink, and discourage refilling/3rd 
party cartridges.

As it turns out, the chip can be reset using a trick involving 
swapping in a full cartridge first, or with electronic devices 
expressly made for the job. Chips can also be recycled after a 
cartridge has been used to the end of its useful life (the foam wears 
out). Unchipped, empty cartiridges are cheaper than ones sold with a 
chip.

See inksupply.com for more detailed explanations (you can also buy 
the relevant products there).
