Gordon says that inkjet ink is obscenely expensive. Leo agrees and it doesn't have to be. That's why printers are so cheap, because they make up for it with ink purchases. Gordon is wondering if it would be worth it to buy inkjet refills. Leo has traditionally avoided refills because the ink usually isn't as good. It also may violate his printer's terms of service, which would void the warranty. Also, some printer cartridges also contain the printer head. Refilling the cartridge won't clean the head and he could end up with more clogs. That's why Leo recommends Laser printers. In the long run, they are much cheaper.
