Twinax Interface
Printing labels on demand from a host
computer
IBM System/3X computers do not start sending data to printers until the printer
file is closed. If you want to send labels that you design on a system terminal
immediately to the twinax interface for printing, you must follow these
guidelines:
IBM System/34 and System/36 If you are using IBM System/34 or System/36,
you need to finish the RPG to close the printer file. OCL statements may be
used to reload the program for the next print job.
IBM System/38 and AS/400 If you are using IBM System/38 or AS/400, you
need to call a separate print program that will print the on-demand label or,
after writing a label, explicitly close the printer file within the RPG program.

Label design

When you print a label with the twinax interface installed in the printer, design
your label's format and data by using a label design software program or your
host terminal. Refer to your printer user's manual for information on label
design at the host terminal.

Example print program

The following pages provide an example RPG print program for the AS/400.
The next few paragraphs provide you with details about the RPG print
program.
File specifications The file specifications used in the RPG example program
are identical to those used for the IBM 5256 printer.
Extension specification The extension specification defines a compile time
array named FMT. The FMT array contains the label format.
Calculations specifications Miscellaneous label fields and printer control
characters are initialized by the calculation specifications. The calculation
specifications also contain the FORMAT subroutine used to send the label
format to the twinax interface.
