C1 Transmit/Receive: Defines the type of C1 processing or
encoding.

ESC SP 6
ESC SP 7
ESC SP F
ESC SP G
Description
These sequences define how C1 codes are encoded from the host to
the printer or from the printer to the host. The sequences select
whether the interface uses 8-bit encoding or 7-bit equivalent (ESC Fe)
encoding. These equivalents are given in the third column of the table
on page 196 .
These sequences are processed in sequence with all other data.
Therefore, it is recommended that software send these sequences
before all other commands to prevent confusion.
If the printer is set to 7 data bits via a setup feature or the front
panel, this sequence is ignored.
The printer recognizes either 8 bit or 7-bit equivalent encoding from
the host. However, it always transmits using the 7-bit equivalent
encoding.
Process 7-bit ESC Fe
sequences. If 8-bit C1
control codes are received,
drop the 8t
as C0.
Process 7-bit ESC Fe
sequences and 8-bit C1
control codes.
Transmit C1 control codes
as ESC Fe sequences. This is
the power-on state.
Transmit C1 control codes
as C1 codes.
