Hello,

Welcome to the monastery.

When you say that everything is working great, have you actually been able to generate and view a .ps file that contains a label with your barcode on it? Are you sure that the problem you're having is CGI, or is it that your postscript file isn't actually correct?

I ask because it seems the PostScript::MailLabels does not support embedding graphics. Take a look at the documentation "todo" section to see that it is planned in the future. So it appears you're just loading up a text field with data that has no hope of being interpreted as a graphic image.

If true, you may have to do your own label alignment code.
