Wire matrix printers print dot characters by firing a print wire 8 against a record medium with an inked ribbon placed therebetween. This procedure leaves a dot on the record medium. To eliminate the ribbon, one could use a print wire 8 made of sintered metal 10 with a hard chrome-plated outer diameter surface 12. Referring to Figs. 1 and 2, suitable sintered metal 10 is formed to the size of existing wires and plated with approximately .0005 to .0007 of hard chrome 12. The print end 14 is etched flat to perform its function. The porous sintered metal core 10 acts as a wick along which the ink will move inside the non-porous hard chrome shell 12.
