ABSTRACT:
The elements of a printing mechanism, including a platen, print head and drive motors, are constructed and arranged to provide a clearance permitting an envelope to remain entirely in a flat condition in a plane tangent to the platen at the location of the printing line while the envelope is being printed by the print head. The housing of the printing mechanism is constructed with specially configured slots. First and second opposite end walls of the housing, and a third wall, extending from one end wall to the other, provide at least partial coverage of the print head and platen. The third wall has a slot extending from one end wall to the other, the slot being arranged to receive an envelope and to allow the envelope to be inserted in a flat condition between the print head and the platen. The end walls have parallel slots, meeting and continuous with the slot of the third wall. The parallel slots of the end walls are aligned with the plane which is tangent to the platen at the location of the printing line, so that the envelope being printed can extend outwardly from the housing through all three slots. The printing accommodates envelopes in a wide range of sizes.
