We have two inkjet printers in our house--an Epson Stylus Color 600 (10 yrs old) and an HP 960CXI (7 yrs old). They still work and I am satisfied with them. When I am at second hand stores, I sometimes see brand new factory sealed genuine Epson and HP ink cartridges for sale, but most often they are expired, sometimes as far back at 2002. They usually sell for $5. I am referring to HP 78 and 45 and Epson S020187 and Epson S2020191 ink. What are the chances of expired ink being good? How far past the expiration date does ink last? Oh and since we're coming up on the biggest shopping day of the year in the United States, what do you all think of light duty inkjet printers these days around $100 vs the printers I have. Has quality improved or declined?
