ABSTRACT:
A printing device for printing characters and codes on surfaces. In one form, the device is contained within a hand-held housing of rectangular parallelepiped configuration having an opening in one of the major surfaces thereof through which opening printing material may be dispensed to form characters or codes against the surface of an article which is adjacent to the opening. A plurality of printing wheels may be employed on a common shaft with each wheel selectively rotated to bring a particular character on the periphery of the wheel into alignment with the opening in the housing after which all of the wheels are simultaneously projected through the opening to engage the surface to receive the printing. In another form, printing material is sprayed or otherwise propelled through the opening in the configurations of characters or code marks to be dispensed against the surface to be printed. A keyboard is provided against or within the confines of the surface of the housing which is opposite that containing the opening and the selective manipulation of the keys thereof controls the printing means to operate and print the selected characters through the opening. Visual alignment means in the form of marks or housing configurations is provided to align the opening in the housing with a selected portion of a surface to receive the printing.
