A computer input system is disclosed that utilizes a glove-type multiple styli device that is mapped for operation based on their finger position. The printing device includes a locked print process that is configured to examine print data received by the printing device and determine whether locked printing is to be used for the print data. The disclosed plastic sensor comprises a plastic substrate, at least one working electrode formed on the plastic substrate, a reference electrode printed on the substrate, and a golden finger printed on the plastic substrate. Moreover, the overhead console is pivotally attached to the front frame member, wherein the overhead console articulates from a first position relative to the front wall of the coach to a second position that is a first distance away from the front wall. An encoding panel projects from the contact lever and away from the recording paper, and is shiftable in response to rotation of the contact lever.
