Abstract
A self-adjusting printing assembly for accommodating generally planar media of differing thickness comprising a printing head for placement of indicia on said media, a guide assembly positioned adjacent said printing head for guiding said media to said printing head. The guide assembly includes a planar platen for continuously supporting one surface of said planar media and a planar shield member fixedly supported with respect to said platen for continuously supporting said surface of said planar media. The assembly also includes means for movably mounting said platen with respect to said shield for movement in a direction toward and away from said planar shield while maintaining said planar platen generally parallel to said shield for accommodating said media of differing thickness, and a drive means for urging said media through said guide assembly and towards said printing head.
