Abstract

The present method provides the determination of the first print position on a workstation printer. Usually, the first print position is determined by both the vertical (Y) and horizontal (X) positions, as shown in Fig. 1.

Method for Setting of the First Print Position On a Printer

      The present method provides the determination of the
first print position on a workstation printer.  Usually, the first
print position is determined by both the vertical (Y) and horizontal
(X) positions, as shown in Fig. 1.

      The present method describes how to determine the X position.
This method is performed by using the two sensors.  One is used for
detection of the left edge of paper, and the other is used for
detection of the margin lever position wanted by the operator.  The
former is defined as edge sensor (A), and the letter is defined as
margin sensor (B). Both the sensors A and B move with the head
carrier.  Fig.  2 shows the physical logistics in accordance with the
present method.

      The determination of the first print position is accomplished
by the relationship of the position between the two sensors and the
home position of the print head.  That is, the datum point of the
margin scale is considered to be the edge of the paper, and the
position of margin lever is defined as the first print position by
the control program. The operator is able to set up the desired print
position easily.

      Note: Initial Print Position is determined by each printer on
its own.

      Referring to Fig. 2, the following numeric formulas represent
the above logistics.  In this case, the forward direction is defined
to be plus (+), and the reverse direction is defined to be m...
