    Abstract: A new bar code symbology in an exemplary embodiment employs three bars (and spaces) within nine modules, similar to Code 93. Fifty-three data characters are defined, including several special mode characters. By employing these special mode characters, together with certain routines, three symbol characters can represent two 8-bit bytes, or one 16-bit word. As a result, the symbology can efficiently encode 8-bit bytes for use in computer processing, or encode 16-bit character sets such as Unicode. Symbology encodes extended channel interpretation (ECI) numbers, provides multiple numeric compression modes, provides a structured append using a single mode character, as well as other features. Additionally, the symbology includes error correction, with a Special Features Flag character indicating use of error correction in a symbol.

    Abstract: A thermal printhead formed on a substrate. The plurality of thermal print elements in the thermal printhead are formed in a linear array. Each of the plurality of thermal print elements is respectively connected to a plurality of common electrode traces and a plurality of ground electrode traces. The common electrode traces are switchably connected to a single common electrode and the ground electrode traces are connected to a single ground electrode. The common electrode is held at a common voltage and the ground electrode is held at a ground voltage. The electrical circuit includes at least one common remote sense electrode connected to the single common electrode and, optionally, at least one ground remote sense electrode connected to the single ground electrode.

    Abstract: An electrophotographic printer especially for bar code printing having an image transfer drum for placing an image onto a continuous form to be printed moved along a path by a form feed. A fusing roller is located downstream to fix the image on the form. The form is fed along a path past the transfer drum and fusing roller and after printing the last printed form is separated from the continuous form downstream of the image transfer drum leaving a leading edge on the unprinted form. The separation of the printed form is signaled to a controller which disables the image transfer device and fusing roller and causes the form feed to reverse moving the new leading edge upstream to a location immediately adjacent the image transfer drum. Various forms of printing, fixing the image onto the form, feeding the form and various types of forms such as barcoded labels on a carrier continuous form are disclosed. A method of printing and retracting a continuous form to utilize the unprinted portion of a form adjacent the last printed portion of a form at the end of a print run.

    Abstract: A method and apparatus for error correction enhancement for machine-readable symbols applies particularly to symbols having symbol characters, repeating characters such as pad characters, and error correction characters derived from the symbol and pad characters. The method and apparatus read a selected symbol where the selected symbol has at least one damaged pad character. After failing to decode the symbol, the method determines that the symbol has at least one damaged pad character and then locates at least two consecutive pad characters in the selected symbol. The method replaces any damaged pad characters, and then again attempts to decode the symbol, using the error correction characters, after the pad characters have been replaced.
