There is a quick and easy way to print using the remaining color inks if you are using Epson printer ink. If the color ink is expended and then you can force Epson printer to print without color ink. But it is recommended to replace the old cartridge with a new one as soon as possible. To do so, open the print dialog, then choose 'Print Settings.' Now, choose 'Plain Paper' in 'Media Type.' Make sure that the 'Slow Drying Paper' option has been unchecked. Then, choose 'Grayscale in Color/ Grayscale.' At last, click 'Print' to begin the print job.
