JPS63193875A - Method for setting right/left printing limit positions in serial printer - Google Patents

Abstract

PURPOSE:To vary right/left margin positions independent of a host device, by providing a means allowing the shift of two carrier sensors directing the left end and the right end, and a switch changing over the carrier sensors between valid/invalid. CONSTITUTION:An operator turns a valid/invalid change-over switch to be valid prior to the power making to previously move two carrier sensors 2, 3 directing the left end and the right end to desired left margin and right margin positions. By setting paper corresponding to the carrier sensors 2, 3, a printing can be started at the positions serving as right/left printing limit positions. In this manner, a left margin and a right margin can be easily determined for any size of paper being mounted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a left print limit position (left margin) and a right print limit position (right margin) of a serial printer.

[Conventional technology]

Conventionally, the left margin and right margin of serial printers were set by the operator in the data sent from the host device, or by using the default values set when the printer was turned on. .

[Problem that the invention seeks to solve]

Therefore, there is a drawback that the left margin and right margin cannot be easily changed by the printer itself, regardless of the host device.

[Means for solving problems]

The left margin and right margin setting method for a serial printer according to the present invention includes means for movable the positions of two carrier sensors indicating the left end and right end, and a switch for enabling and disabling the carrier sensors.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a schematic diagram of an embodiment of the present invention. 1 is a conventional home sensor. 2 is a movable carrier sensor A indicating the left edge, 3 is a movable carrier sensor B indicating the right edge, and 4 is the movable range of the two carrier sensors A and B, and two other carrier sensors are enabled. There is a switch to disable it. When the left margin and right margin settings are enabled/disabled switch is enabled, after homing is completed by turning on the power, two movable carrier sensors indicating the left and right edges are printed to detect people and B. The head is spaced, and the sensor A detection position is set as the left margin, and the sensor B detection position is set as the right margin. When the enable/disable switch is disabled, only homing of the print head is performed, and spacing for detection of the two carrier sensors indicating the left and right edges is not performed, and the left margin is set to the leftmost edge and the right margin is set to the Set as the right edge.

Before turning on the power, the operator must enable the enable/disable switch and move the two carrier sensors indicating the left and right edges to the desired left margin and right merge positions.

Next, when the operator sets the paper in line with the two carrier sensors that have been moved, printing can be started using those positions as the left and right printing limit positions.

〔Effect of the invention〕

As explained above, the present invention provides a serial printer with two movable carrier sensors A and B that indicate the left and right edges.
Furthermore, by using a combination of switches for enabling and disabling the two carrier sensors, it is possible to easily set the left margin and right margin for any paper size.
