7–14 Digital Emulation
Parameters are interpreted as unsigned decimal integers with the most
significant digit first. Parameter values greater than the maximum allowable
65535 will be set to 65535. Do not use a decimal point in any parameter —
the printer will ignore the entire command. If no value is specified, zero (0)
is assumed. A value of zero or an omitted parameter indicates the printer
default value should be used for that sequence.
If the printer receives the parameter characters 3AH, 3DH, or 3EH anywhere
in the parameter string, it performs no action until the final character is
received, then ignores the entire sequence. These parameter characters are
sixel control codes and must not conflict with CSI sequences.
A CSI sequence containing one or more group(s) of invalid parameters is still
processed, but only the valid parameters are used. If all parameters in a
sequence are out of range or invalid, the printer waits for the final character,
then ignores the entire sequence.
Intermediate and final characters define the control function. For example,
the sequence, ESC [ 3 m (hex 1B 5B 33 6D), turns italic printing on. This
sequence uses one selective parameter [3], no intermediate characters, and
the final character [m].
The LG06 and LG12 process control sequences with one intermediate
character only. If more than one intermediate character is received, the
printer waits for the final character, then ignores the entire control sequence.
If no intermediate characters are in the sequence, the final character
determines the control function.
