Connecting a printer to the NT631/NT631C enables printing of hard copies of the currently displayed screen (printing of screen images), and, by system menu operations, printing of the screen display history and alarm history.

The following types of data can be printed, depending on the printer con- nected to the NT631/NT631C. 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 Program- mable Terminal Reference Manual.)

•Screen display history record data (page 194)

•Alarm history record data (page 196)

3-3-1 Connection Method

Connect the printer to the NT631/NT631C with a Centronics cable, as shown below. The length of the cable should not exceed 1.5 m.

Reference:

Recommended Connector Cable

The following connection cables are recommended.

NT-CNT121 (1.5 m, 20-pin to 36-pin), made by OMRON

Recommended Printers

When using a printer, use one that can emulate an NEC PC-PR201H (us- ing the NEC PC-PR201PL control protocol) or complies with one of the fol- lowing EPSON control standards: ESC/P 24-J83C (color), or ESC/P 24- J82 (monochrome).

When using a monochrome printer with an NT631C, set Tone printing with the NT631C memory switches (page 169).

3-4 Connecting a Bar Code Reader

Connecting a bar code reader to the NT631/NT631C enables bar code data to read as character strings into character string input fields, and set in char- acter string memory tables.

In order to use a bar code reader, the Comm. A Method memory switch must be set to Bar-Code Reader.

For details on the method for inputting character strings with a bar code reader, refer to 3-7 Input of Numeric values and Character Strings in the NT31/NT31C/NT631/NT631C Programmable Terminal Reference Manual.
