Printing barcodes from a website

Hello
I need to print barcode labels from a label printer, using a control on a website. Is there a way to print to a specific printer? We are thinking of moving our inventory controls to our internal web pages, but formatting and printing labels is holding it up. any suggestions?

Have you seen these?
