Take a look at EPSON printer driver, which prohibits you from:

1. Sharing the printer you own with anyone else unless they agree to the license of the driver (incl. business setup)

2. Sharing the printer over the internet unconditionally, because this allows to use the driver for people who did not agree to the license

3. Incorporating the driver in any "revenue generating product or service"
