664 Ink Printer Compatibility
Start with a new printer
Paper Saver 664 ink is compatible with printers that use Epson 664 ink. The ink comes in a bottle for filling the ink tank in the printer. You should start using Paper Saver ink with a new printer that has clean, empty ink tanks. If you put Paper Saver ink in printer that had regular ink in it before, the old ink will contaminate the Paper Saver ink so that it is no longer self-erasing. The mixture of inks will typically clog the nozzles in the printer and make it unusable.
The Epson L121 and L120 printers are compatible and is available on eBay from Taiwan with fast shipping.
Other compatible printers that Epson has discontinued are: ET-2500, ET-2550, ET-2600, ET-2650, ET-3600, ET-4500, ET-4550, and ET-16500, ET-14000, L110, L120, L200, L210, L220, L300, L310, L335, L350, L355, L364, L365, L382, L455, L555, L1300 You can buy these printers wherever you like.

Epson uses different model numbers for printers in different regions of the world. Unfortunately that means you will have to do your own research where you live to find the correct printer for 664 ink.
