ABSTRACT:
A print engine suitable for printing barcodes and other patterns using charged inks includes a semiconductor memory layer having memory circuits that are coupled to one or more line elements and/or printel cells. The printel cells and line elements either attract or do not attract charged ink based on the data stored in the corresponding memory circuit. The line elements and printel cells may be configured to form a linear barcode or a 2-dimensional barcode. The charged ink may also be electrically conducting and the line elements and printel cells may be configured to form electrical structures such as electrical circuits or antennae. The charged ink may also be electrically semiconducting and by the line elements and printel cells may be configured to form electronic semiconductor devices and circuits.
