Stationary printhead with moving platen |
摘要 |
Accordingly, an apparatus has been provided for printing identifying indicia on a work product. The apparatus includes a print mechanism and a transport for imparting relative motion between the work product and the print mechanism. The work product and the print mechanism are positioned in close proximity to one another. A control is provided for causing the print mechanism to print predetermined identifying information on the work product when the work product and the print mechanism reach a desired location as they move with respect to each other. In the preferred embodiment the print mechanism has a fixed print electrode with a moving resistive ribbon associated therewith. A track is provided for supporting the work product on air bearings. A moving vacuum belt moves the work product along the track and thereby moves the work product with respect to both the print electrode and the ribbon.
