The problem turned out to be that the poppler-utils package was installed, but xpdf-utils was not. The -cfg option to pdftops is only supported by the version of pdftops in xpdf-utils.
I never installed poppler-utils manually - it must have been brought in by another package dependency. Thus I think this is a dependency issue with Cupsys. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
