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.

3.4 IEEE 1284 Parallel Interface

The parallel interface for the CL408e/CL412e 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

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.
