Your printer may refuse to print if there is no paper in the tray or if the paper is loaded incorrectly. Remove the paper, align the sheets properly, and place them back into the tray. Also, check inside the printer for jammed paper. Even a small torn piece of paper can block the printing process. Carefully remove any stuck paper without damaging the internal parts.
