6.1 Printing Barcodes on KonicaMinolta BizHub

I'm trying to implement bar-coding and cannot print readable barcodes on our
KonicaMinolta BizHub 7145. It's trying to print, but the line height is so
small you can't read it. Changing font size and adjusting the field height
doesn't have any affect. The Dataworks Bar 39 font is installed on the
copier. The bar codes print fine on HP and Brother laser printers.

KonicaMinolta hasn't been any help - seem to be clueless.

Anybody printing barcodes on this type of copier/printer?

thanks,
