PIXMA TS6020 "Printer in use" only it isn't

[Lesieli]

My TS6020 has suddenly decided that it was in use and wouldn't print anything. I noticed the ink lights are not on. 

I tried unplugging and replugging the printer, the router, the modem, and rebooting the computer. Then removing the printer from the list and installing it and downloading a new driver. Nothing works. 

Have I missed something or is it time for a new printer?

Greetings,

What OS and build are you using this printer with?

What is it connected to and how?

Did it work previously and if so what has changed.
