My Epson Stylus printer has stopped printing one or more colours, even though the ink levels are OK. Do I need to reinstall or reconfigure the driver?
The most likely cause is a blocked inkjet nozzle. Make sure you have the escputil package installed, then run a nozzle check: $ sudo escputil -n -r /dev/usb/lp0 …assuming your Epson Stylus printer is the first USB printer. If not, use the appropriate printer device name. Should you discover colours are missing from the nozzle check pattern, run a head clean: $ sudo escputil -c -r /dev/usb/lp0 Then run the nozzle check again. You may need to do the head clean a couple of times to get printing to work perfectly.
