Abstract

A very convenient, low cost storage medium having long life, requiring little space, and not subject to power failure is provided by printing a sheet of paper with machine-readable information. A printhead 1 has adjacent electrodes (not shown) connected to a printhead driver 2 by conductors 3, 4, 5, 6, 7, and 8, for example. The number of the conductors is equal to the number of electrodes in the printhead 1, and the six conductors 3-8 are an example since the printhead 1 could include forty electrodes, for example. The printhead 1 causes printing on a sheet of paper through heating a thermal transfer ribbon by selectively energized electrodes to cause conductive ink to be placed on the sheet of paper to print thereon a desired character or other data, such as a bar code broken up into bits, for example.
