I do the modification after a systemd stop cups.service

Yes, this one: http://energenie.com/item.aspx?id=7415&lang=en
Works well with the sispmctl package.

I was not aware of that, I need to dig into more detail here in the next days.
The printer is a HP CP1525NW.

Yes, a prehook and the TEABILLING shows in the stack trace, I am not using it
intentionally at all...
Aaah...now I see what went wrong: My orignal post contained the information,
but it seems only in the HTML view, not sure why kmail decided to leave out
this information in the text representation :-/ Avoided HTML view now in this
mail, sorry for that.
For easier reference I append the previous post:
I have tea4cups configured to power on my printer before printing. In order to
do this, I prepended tea4cups:/ to the DeviceURI in printers.conf (if I remove
this and power on the printer manually before printing, everything works as
expected):
/etc/cups/printers.conf:
DeviceURI tea4cups:/http://hpljwlan:631/ipp/
I configured the printer power on script:
/etc/cups/tea4cups.conf:
prehook_sispmctl : /usr/local/bin/printeron
but I get unfortunately an error in /var/log/cups/error_log
with every print job and the job is stopped.

Is seems something goes wrong while setting the TEABILLING environment
variable.
