Abstract

This apparatus provides a high-speed printer with an infinite character set generated by the use of dots. The printer prints a subline of up to 1320 dots across the standard 132-character page width. Ten sublines of print are required for a standard line of English print. The character shape, size and spacing are program dependent. This feature allows the printer to be excellent for graphics.

High Speed Infinite Character Set Printer

This apparatus provides a high-speed printer with an infinite character set generated by the use of dots. The printer prints a subline of up to 1320 dots across the standard 132-character page width. Ten sublines of print are required for a standard line of English print. The character shape, size and spacing are program dependent. This feature allows the printer to be excellent for graphics.

The preferred embodiment is shown in Fig. 1. There are 1320 hammer driver assemblies arranged in line. These may be fired simultaneously or ripple fired to reduce power supply requirements.

As illustrated in Fig. 2, another row of 1320 hammer driver assemblies may be spaced an odd number of lines apart, thereby permitting two lines to be printed at once and doubling the space of the printer.
