Introduction
UBI Direct Protocol is an easy-to-use printer programming lan-
guage that has been developed for use with the computer-control-
led direct thermal and thermal transfer printers manufactured by
United Barcode Industries (UBI).
UBI Direct Protocol can be used in two ways:
• To create label layouts consisting of fields with fixed or variable
information. A layout can then be selected and provided with
variable input from the host computer in the form of a simple
string of data.
• To send input data and formatting commands as a continuous
string of data directly from the host computer.
In both cases, UBI Direct Protocol provides a flexible error handler,
which allows you to compose your own error messages in any lan-
guage.
UBI Direct Protocol has been created with two main types of appli-
cation in mind:
• Applications where the end-user requires a simple printer control
program, but needs a versatile error handler.
• Applications which have a comprehensive printer control program
in the host computer.
Refer to chapter 13 in this manual for lists of the various commands
in UBI Direct Protocol.
