Application Instructions A-4
Escape Sequence — Z-Axis Printhead Position
Escape sequence: ESC DLE zSNN
Hexadecimal: 1B 10 7A SNN
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.
