Introduction

This chapter describes printing in each of the emulation modes, with an example of

printing using VTerm in VT-220 emulation mode.

Printing under IBM 3270 & 5250 Emulation

General

The appearance of a Flag Byte at a specific Flag Row and Flag Column position in the

screen causes the handler on the NCU to take all characters after the flag byte, up to the

next appearance of the flag byte, and send them to the printer on the terminal.

After the printer data has been sent, the handler sends the specified Response Key to the

host application. At this point, the host application must clear the printer data from the

3270 screen, or replace it with the next set of printer data.

For the purpose of initializing a printer and for testing print data, an Init File text file can

be placed on the NCU in the

/crf directory. The contents of this file will be transmitted

to the terminal when the RF terminal attaches to the IBM handler on the NCU.

IBM Handler Configuration

1. Refer to the “Printer” section on Page 1 of the 3270 and 5250 Handler setup screen.

2. Set the printer type as appropriate.

3. Set the decimal value of the ASCII-converted “Flag Byte” to be used by the host

application.

4. Set the zero-based row and column for the Flag Byte. For example, a host 3270

application set for row 1, column 1 is Flag Row 0, Flag Column 0 within the handler

setup.

5. Set the Response Key that signals the application to either remove or replace the

print data from the screen.

6. In the event the printer requires initialization data and/or the actual print data must

be tested for validity, enter the name of the file in the

Init File field.
