[Word] Barcode fonts? Code39 and Datamatrix

Hello, We have HP laser printers and they have the barcode module. Now, i am wondering how to "type"/create barcodes in office..? Do i need to buy special fonts or is there a way to this freely with Office or by creating PCL or postscript code that the HP printer and module can understand? What's happening is that we are getting a PDF from some vendor and we are wasting a lot of label paper since sometimes pages have only 1 or 2 labels entered. We can copy and paste or even import sections of this PDF into word, but the barcodes get translated into the string form. Thanks for any inputs.
