B7332 requires a TTF for viewing the PDF file, however, JDE requires you to have a barcode softfont installed on your laser printer to be able to print through JDE filters (ie, not through acrobat). The config is under menu GH9013, and softfonts in both PostScript and PCL format can be bought from http://www.riversedge.com/ - the Postscript fonts are in the HP UNIX PFA package, I believe. Once you have downloaded the fonts into your printer, you can start printing using them from oneworld printer filters.
In Xe, you don't need PostScript softfont, just a TTF. But if you want PCL barcodes, Xe still needs the softfonts for the printer.
