Printer cartridges very good price and good quality. And you can refill also the same place, same printer cartridge.

What did Impression do, exactly?

Companies like Impression make money by buying up old toner cartridges, refilling them with more toner and then selling them at a lower price than what Lexmark charges.

Lexmark argued that by refurbishing and reselling its cartridges without permission and outside the terms of Lexmark's service agreement with end-users, Impression was violating the patent that Lexmark held on the cartridges. Essentially, Lexmark was saying that its patent rights extended beyond the initial sale of the cartridge to cover even future resales.
