As to the wiring for the interface, be sure to use a twisted-pair cable for each signal and
never fail to connect the return side. To prevent noise, cables should be shielded and
connected to the chassis of the host computer and the printer.

NOTES : In Table 1-14, it is assumed that no ERROR status exists other than
that attributable to the
OFF-LINE mode.
2. Once the printer is deselected by the
code, the printer will not revert to the selected
state until the
code is input. (In the deselected state, input data is ignored until
is received.)
3. The
and
codes are enabled only when the
signal (Input Connecter Pin
No. 36 when the parallel interface unit is used) is HIGH and the printer is initialized.
4. The
signal is “LOW” when the printer is initialized. At this time the
printer select/deselect control is invalidated, and these control codes are ignored.
