Your company's advertising department is complaining that their printer is not printing the correct colors. Which of the following approaches can you take to address this issue?

Sometimes using off-brand ink and toner works fine, and sometimes it doesn't. It's close enough for most of us, but not for an artist. Use ink or toner designed exclusively for that printer's make and model. Another quick repair is to make sure that the printer is set to better quality rather than faster speed. The exact actions you take depend on the printer being utilized. Paper orientation has little to do with color, and while you may need to reinstall a faulty printer driver, deleting and reinstalling the printer to correct a color problem is not quite a thing to do.
