Dave has an Epson printer and it keeps getting clogged up, prompting him to have to run the cleaning utility, which wastes ink. Leo says that people hardly print anymore and it could be that since Dave doesn't print all that often, that the printer head has dried ink inside it which is causing it to clog. Replacing the head would work, and some people even replace the heads every time they replace the ink cartridge. That's a better way to do it. But if he doesn't print all that much, a laser printer may be a better long term option.
