3-3 Connecting a Printer
Connecting a printer to the NT31/NT31C enables printing of hard copies of the
currently displayed screen (printing of screen images), and, by system menu op-
erations, 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 (Refer to information on printing data and checking
the printer status in the NT31/NT31C/NT631/NT631C Programmable Termi-
nal Reference Manual.)
• Screen display history record data (page 198)
• Alarm history record data (page 200)
3-3-1 Connection Method
Connect the printer to the NT31/NT31C with a Centronics cable, as shown be-
low. 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

Recommended Printers
When using a printer, use one that can emulate an NEC PC-PR201H (using
the NEC PC-PR201PL control protocol) or complies with one of the follow-
ing EPSON control standards: ESC/P 24-J83C (color), or ESC/P 24-J82
(monochrome).
When using a monochrome printer with an NT31C, set Tone printing with the
NT31C memory switches (page 174).
