I want ti print in color only,how do i do that,?Lexmark X1240 All-In-One InkJet Printer

On your computer, with your file open (your document/picture, etc. that you wish to print), click File > Print. From Print dialog box, click Properties, Preferences, Options, or Setup (depending on the program). The Print Properties dialog box appears. From the Quality/Copies tab, make sure there is no check mark in the "Print Color images in Black and White ". Then hit OK button to save the setting. Once you print your colored document/pictures, etc, it should come out in color.
I hope this helps.
