Escape Sequence — Z-Axis Printhead Position

Escape sequence:

ESC

DLE

z

S

NN

Hexadecimal:

1B

10

7A

S

NN

where:

S = “+” or “-” as the sign of the displacement (positive or negative).

NN= ASCII values of the two digit number of the range from initialization.

Note: The escape sequence ESC DLE z, followed by any code, other than specified for the next three characters, calibrates the printhead to the Z-axis initialization.

Using the Z-Axis Escape Sequence

A single example is provided for 880 printer emulation that illustrates the considerations for Z-axis adjustment and maximum throughput. This is the most complex because printing requires that another emulation mode be entered to obtain reverse paper motion to provide maximum throughput rather then making several Z-axis adjustments for possibly four lines.
