Unfortunate. Is this always reproducible?

I should have been a bit more helpful initially:

https://wiki.debian.org/DissectingandDebuggingtheCUPSPrintingSystem#The_CUPS_Error_Log

Basically - empty the error_log and print. I suggest that you print as I
described in my previous mail to test the wrapping function. That is, no
hooks used. The data would still be useful to have.

Upstream has now put the patch in trunk:

http://svn.pykota.com/tea4cups/trunk/tea4cups

os.environ["TEABILLING"] = self.JobBilling or ""

        try :
            self.JobBilling = str(self.JobBilling) # In some cases it seems to be an integer : bug in pkipplib or something else ???
        except :
            pass

Regards,

Brian.
