I have found cause of my problem.
1. I edited /usr/sbin/jetpipe, to preven it from forking.
2. I launched /usr/sbin/jetpipe -b 9600 -y 8 -p none -x /dev/usblp0 9100 on TC
3. I send some jobs to printer.
4. While printing i swiched off an on printer.
5. I sow the following in terminal:\
--------------------------------------------------------------------------------------------------------
r...@ltsp26:/usr/sbin# /usr/sbin/jetpipe -b 9600 -y 8 -p none -x /dev/usblp0
9100
/dev/usblp0 9100

Traceback (most recent call last):

self.device.flush() # parallel device

Unfortunately i'm not familiar with python, but i think that there
should be exeption handling cunstruction (like try-catch) in this
snippet of /usr/sbin/jetpipe:
(line 28) self.device.write(data).....
