When you try to copy or scan a document on your printer, you will see a screen asking you to confirm the details of the job. Here you can select whether the job is single or double sided, whether you want it in colour or black & white etc. You will also see a tab near the top of the screen labelled “Copy Settings” or “Scan Settings”, clicking on it allows you to change other settings for the job, such as the resolution, ink density, etc.
