There is no need to know or do your application differently because you are using barcodes only to represent data that could otherwise be printed . Symbolology and dimensions can be settled in a contemporaneous separation layer, which you put together when you need it.
-
Symbologies are usually set by spot requirements, such as customer standards, industry standard, etc. If it is for internal use, then code 3 is generally considered to be a good default.
-
For printing, most of the requirements are available from many sources including laser printers, special label stocks, and downloadable fonts special printers Zebra, intermax, etc; But these are more expensive, and you need to print on ownership (read: expensive) paper.
-
Fonts are usually Google for "barcode fonts", but one of the easiest options is that most of the postcrypt printers are most commonly used in any dimension Will be symbolized.

Reading the barcode to read the barcode with a PC input device, usually it is either your normal open / close / read / written / ioctl equivalent, or your actual keyboard As a surrogate keyboard is implemented with the available device driver inline, so the input key appears as a stroke (optionally with the terminal Newline.) The non-PC devices have their own There are programming requirements.
