Barcode DLL

all symbologies in one DLL

printer independent

and fast!

TEC-IT Barcode DLL adds Bar Code Generation to C/C++, Delphi, Visual Basic,...

  • You are a software developer and want to print bar codes or barcode labels from within your application?
  • You want to integrate bar codes fast and without problems?
  • A barcode font would not be flexible enough? You prefer to copy only a DLL to your clients - and that's all?
  • Bar code functionality should be integrated as tight as possible?
  • But check digits, module width, font, bar/space ratio, subset control, AI's, orientation, and more parameters should be adjustable on demand?
  • All linear bar codes like Code 11, Code 39, Code 128, EAN, UPC, Codabar, Postnet, and more (...) should be integrated within one DLL
  • And the powerful 2D-symbologies like Data Matrix, Maxicode and PDF417, too?
