Abstract

A technique is described whereby a single printing unit integrates two distinct printing capabilities - dot matrix printing and fully formed character printing - into one operational unit. The single printing unit consists of housing 10, as shown in the figure, which contains printwheel actuating mechanism 11, wire matrix actuating mechanism 12 and inked ribbon mechanism 13. During the printing of fully formed characters, wire matrix actuating mechanism 12 is retracted away from the paper and ribbon enabling printwheel actuating mechanism 11 to be positioned so as to allow its printwheel 14 to rotate. The rotation of printwheel 14 will allow a character pedal 15 to be positioned to the top location for printing. Once positioned, wire matrix actuating mechanism 12 allows its wires to strike pedal 15.

Integrated Dual Technology Printer

A technique is described whereby a single printing unit integrates two distinct printing capabilities - dot matrix printing and fully formed character printing - into one operational unit. The single printing unit consists of housing 10, as shown in the figure, which contains printwheel actuating mechanism 11, wire matrix actuating mechanism 12 and inked ribbon mechanism 13. During the printing of fully formed characters, wire matrix actuating mechanism 12 is retracted away from the paper and ribbon enabling printwheel actuating mechanism 11 to be positioned so as to allow its printwheel 14 to rotate. The rotation of printwheel 14 will allow a character pedal 15 to be positioned to the top location for printing. Once positioned, wire matrix actuating mechanism 12 allows its wires to strike pedal 15. Pedal 15 then strikes against ribbon 13 to print a fully formed character 16 onto paper 17. During dot matrix printing, printwheel 14 is positioned so that gap 18 will allow wire matrix actuating mechanism 12 to be moved toward the paper so that wire matrix wires 19 will project through gap 18, allowing the wires to strike ribbon 13 to produce wire matrix characters, such as 20, onto paper 17. Interposer devices are used to provide the printing registration required and to prevent damage to the matrix print wires.
