ABSTRACT:
A printing machine comprising a flat, substantially horizontal, guide portion on which the document to be printed is initially placed, a curved guide portion connected with the horizontal guide portion across which the document may be pushed manually and a final vertical guide portion connected with the curved guide portion providing a vertical passage across which a print head traverses for the purpose of printing on the document as it moves upwardly through the vertical passage. Drive rolls are provided in the vertical passage just above the line of traverse of the head for first continuously pulling the document upwardly through the passage once it has been manually pushed to this point and then incrementing the document upwardly through the machine and in the vertical passage for each of the lines of print provided by the print head.
