Selects either pre-directional printing, bi-directional printing, or uni-directional printing.

42 PRINT DIR

•Pre-directional printing:

Whenever a double pass of the print head is required, the direction of the second pass is the same as that of the first pass . This logic - seeking, unidirectional printing can be used, therefore, in modes such as double strike and double height printing. The logic seeking capability is executed before the first pass of the print head. The printing direction of all paths is the same as that of the first pass.

•Bi-directional printing:

Successive passes of the print head alternate between the left-right and right-left direction.

•Uni-directional printing:

Data is always printed in a single direction from the left to the right. This selection on the front panel will ignore a software print direction command.

When unidirectional printing is set, a software command with respect to the printing direction is not accepted. When pre-directional printing or bidirectional printing is set, a software bidirectional command is executed.
