3.4 IEEE 1284 Parallel Interface
The parallel interface for the CL608e/CL612e printers is a Plug-In Interface Module that
can be installed by the user. It conforms to the IEEE 1284 specification. It will
automatically detect the IEEE 1284 signals and operate in the high speed mode. If it
does not detect the IEEE 1284 signals, it will operate in the standard Centronics mode,
which is significantly slower. For this reason, an interface cable and host interface
conforming to the IEEE 1284 specification must be present to fully utilize the speed
capabilities. This interface also operates bi-directionally and can report the status of the
printer back to the host.
Electrical Specifications:
Printer Connection AMP 57-40360 (DDK) or equivalent
Cable Connection AMP 57-30360 (DDK) or equivalent
Cable IEEE1284 Parallel, 10 ft. (3 m) or less
Signal Level High = +2.4V to +5.0V
Low = 0V to -0.4V
Data Streams:
<ESC>A .. Job#1 .. <ESC>Z<ESC>A .. Job#n .. <ESC>Z
All printer error conditions (i.e., label out, ribbon out) will cause the printer to go busy
(DTR "low" or X-Off) until the problem is corrected and the printer is placed online. The
printer will also be busy if taken offline from the front panel.

Please Note:
SATO does not recommend the use of mechanical data switches commonly called A/B
switches, as they are known to damage both the computer and printer parallel ports.
