[Koha] koha barcode labels - too much space between text and barcode

Hello all, I'm trying to print out barcodes labels. The problem is that, whatever I try, I get labels with too much space between the text (title, call number, etc.) and the actual barcode. They all look like this: title call number <blank line> <blank line> <blank line> <barcode> As a result, the text does not fit on our labels. Has anyone run into this problem? We're running Koha 3.0. Alternatively, does anyone know of a way to generate barcodes using a 3rd party tool? -- Please avoid sending me Word or PowerPoint attachments.
