Abstract

The drawing shows a print-position display of small size which can show the position within a print line as well as other information. The vertical line 1 is permanently inscribed, while the margin scale and digital information is generated from selectable optical devices.

Printer Position Display

The drawing shows a print-position display of small size which can show the position within a print line as well as other information. The vertical line 1 is permanently inscribed, while the margin scale and digital information is generated from selectable optical devices.

A display of the operative print position away from the print area is especially desirable in word processing systems having other separate displays. In a typical system of that kind, the printer has a typewriter-like carrier for a printhead and the position display shows the carrier position relative to the standard margin scale. Overall operation is much like standard typing.

The margin scale shown follows the form of standard typing because a representation of the usual vertical lines and digits of a margin scale is created at the separate display. Preferably, the scale is developed from a bank of liquid crystal devices (LCDs). Standard logic or data processing provides control signals which activate the LCDs to develop vertical lines and digital information to show the margin scale for a limited length on each side of the carrier or other print position. On the display, the permanent vertical line represents the print position.

A small part of the margin is represented which seems to move with movement of the carrier. Additionally, other information, such as print pitch, shift position and the like, is readily displayed using the optical devices. depending on the pi...
