okay... it happens *regardless* of what application I use to submit the job to CUPS (cupsdoprint does nothing else but submit the job through IPP)

the behaviour is
- submit directly through the filter driver *behind* CUPS: it works fine
- submit through CUPS: it gets mangled horribly

THe only thing I want to understand is how and why it gets mangled and what could influence this process
