Ability to range check user input, Ability to access database stored in printer – AMT Datasouth 4600 User Manual

The Standalone Application program is stored in the printer memory and can

accept input from a PS/2 keyboard, bar code scanner, or other serial devices
such as an electronic scale. These programs may use the printer‟s LCD to

prompt for user input and may also include databases. Unlike other bar code

printers that allow basic static forms to be loaded in the printer, PAL

Print and

Program capable printers provide advanced abilities. Examples of these

advanced capabilities are:



Ability to operate on line from host or off line in stand-alone mode



Ability to range check user input



Ability to combine data from multiple fields into a single bar code



Ability to access database stored in printer



Ability to perform math calculations (addition, subtraction, multiplication,

division, etc.)



Ability to perform logical calculations (equal to, less than, greater than, etc.)

Shown below is an example where a stand-alone PAL

application and

database is stored in the printer. Operator input combined with internal database

information is used to create a label. For example, this application could request

a part number and physical dimensions of a particular part by prompting for this

information on the printer LCD. After the operator inputs the requested

information on the PS/2 keyboard, the printer could calculate the volume, and

then based on the part number lookup the part description in a database to

produce a label.
