To highlight the versatility of this technique, we print single and multi-layered patterns on to various arbitrarily shaped objects: (1) hard, conformal, (2) flexible and (3) soft, conformal substrates, even with sharp angles; Supplementary Fig. 8. We note that the process is most proficient when printing on surfaces with limited curvature. Certain shapes, especially 3D concave surfaces (e.g. the inside of a dome), are difficult to print on using this method. In demonstrating the ability to print on hard conformal substrates, we create spiral conductive graphene patterns directly on to the surface of a glass beaker (figure \[panel3\]a) and on a 3D-printed dome made of polylactic acid (PLA), a thermoplastic; Fig. \[panel3\]b. In both cases, the resulting prints yield continuous lines that are electrically conductive in their entirety without damaging the original dimensions of the pattern (R$_s$ $\sim$120 $\pm$10 $\Omega$ $\square^{-1}$ at $\sim$25 $\mu$m before and after transfer). Overall, the process is suitable for most hard surfaces and there is no significant change in the dimensions of the printed lines at $\sim$25 $\mu$m thickness or structures before and after printing. Large-device prints (130 mm $\times$ 130 mm) can also be achieved, especially on the glass
