3-3 Connecting a Printer
Connecting a printer to the NT31/NT31C enables printing of hard copies of the cur-
rently displayed screen (printing of screen images), and, by system menu opera-
tions, printing of the screen display history and alarm history.
The following types of data can be printed, depending on the printer connected to
the NT31/NT31C. For details, refer to the pages cited.
- Hard copies of the screen (8-11-1 “Printing the Screen” in 8-11 “Printing Data
and Checking the Printer Status”, page 555)
- Screen display history record data (page 219)
- Alarm history record data (page 221)
3-3-1 Connection Method
Connect the printer to the NT31/NT31C with a Centronics cable, as shown below.
The length of the cable should not exceed 1.5 m.
Reference: If the connector cable is connected or disconnected while the power to the printer
is on, the NT31/NT31C may malfunction. Always turn off the power to the printer
before connecting or disconnecting the cable.
