[STR New]

When I cancel the print job via http://localhost:631 interface on my Debian
GNU/Linux system, I can see, that data are still transmitted to the
printer. It is not the problem with the internal printer cache, because
even multiple switching the printer on/off doesn't help.

When I investigated the processes running with the "#ps uxa" I could see
the following process still alive:

lp        6288  0.2  0.9  30544 19180 ?        S    21:02   0:00 gs
-sstdout=%stderr -dBATCH -dPARANOIDSAFER -dNOPAUSE -sDEVICE=hl1250
-dEconoMode=0 -dSourceTray=0 -sOutputFile=%stdout -_

So it seems, that cups doesn't kill the processes run by the lpd to send
the data to the printer...

The configuration of my printer in /etc/printers.conf is as follows:
<Printer hl1430>
Info hl1430
DeviceURI parallel:/dev/lp0
State Idle
StateTime 1212520018
Accepting Yes
Shared Yes
JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0
OpPolicy default
ErrorPolicy stop-printer
</Printer>

I attache the gzipped PPD file.
