Block Letter Printing with Wire Matrix Printer

The drawing shows a set of special characters for a wire matrix printer for printing large block characters.

A typical wire matrix printer has 56 wire printing elements arranged in a matrix having 8 rows and 7 columns. An individual character requires only a few of these elements, and the print mechanism may be limited in the total number of wire elements that can be driven at one time. The special characters shown in the drawing are constructed for a printer that prints any 4 of the 7 not adjacent positions in each row of a character position.

The special character set is made up of an effectively solid block 2, triangles 3 and 4 and two opposite triangles that are not shown, and two diagonal lines 5 and 6.

The printer is programmed to print the special characters in a pattern to represent a selected letter or other symbol. These special characters are particularly useful in printing letter codes on adhesive labels, where it may be difficult to read the large characters that are conventionally made up of the same small letter or other standard characters.
