Is it really possible to create labels with barcodes and not use special third party barcode packages?

With Label Direct, we have incoporated a process within the Brother PT-9700PC/PT-9800PCN Printers that allow us to utilize existing utilities built into the printers. This eliminates having to use special drivers in allications using .NET or other similar environments. There are special commands for these printers and OTS has simplified the process.  Barcode formats supported are: Code 39, ITF, Interleaved 2 of 5, UPC-A, UPC-E, EAN-8, EAN-13, Codabar, NW-7, Code 128, UCC/EAN 128, POSTNET, ISBN-2, ISBN-5, GS1 DataBar, RSS, PDF-417, QR Code, Micro QR, Data Matrix, Maxi Code
