A method of transfer printing comprises globally heating an array of stamps, where each stamp comprises a shape memory polymer with a light absorbing agent dispersed therein, and pressing the array of stamps to a donor substrate comprising a plurality of inks. Each stamp is thereby compressed from an undeformed adhesion-off configuration to a deformed adhesion-on configuration. The array of stamps is then cooled to rigidize the shape memory polymer and bind the plurality of inks to the stamps in the deformed adhesion-on configuration. The plurality of inks remain bound to the stamps while the array of stamps is positioned in proximity with a receiving substrate. A selected stamp in the array is then locally heated using a concentrated light source. The selected stamp returns to the undeformed adhesion-off configuration, and the ink bound to the selected stamp is released and transfer printed onto the receiving substrate.
