jaunty ltsp - Usb printer local - not print

I'm with the same problem....

Printer state: Processing - Recoverable: Network host 'ws001' is busy; will retry in xx seconds...

why did you replace jetpipe ? jetpipe changed massively between hardy (8.04) and jaunty (9.04).
the changes in bug 224259 *only* apply to hardy (8.04)

the lts.conf settings of your second example are from ltsp4.x and dont apply at all to ltsp5.x as used in ubuntu.
please use the most recent upstream documentation for your setup

Oliver, I reconfigured again, but didn't work yet....
It's with the same message.
The print is installed on LTSP Client usb.
My LTSP sever doesn't get to print in it.

Sorry, but I don't speak english very well.

Perhaps this serves to them is not the best thing it solves but it, must sacrifice its installation.
They install the Alternate version CD 8.10 and Update to 9.04
it worked to me.

I confirm this bug.
After a while printer is not printing, and status is "Processing - Recoverable: Network host 'ws001' is busy; will retry in xx seconds..."
I checking if jetpipe is running on 'ws001' - and there is no jetpipe. After TC reboot jetpipe is launched and printer working for a while. After some time error is repeat.

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:\
--------------------------------------------------------------------------------------------------------
root@ltsp26:/usr/sbin# /usr/sbin/jetpipe -b 9600 -y 8 -p none -x /dev/usblp0 9100
/dev/usblp0 9100

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).....

Ok. I edited jetpipe:

            self.device.write(data)
            if self.devicetype == 'P':
                try:
                    self.device.flush() # parallel device
                except device.error, msg:
                    print "error flush(): ", msg

And now switching off printer is not causing jetpipe to crash. But also i don't see my print "error flush(): ", msg. I not python programmer, so if anybody can help me to fix this bug in jetpipe - fill free.

Users in our office often switch off printer device, when it starts to print wrong document, and after switching on it stops print anything. So this bug should be solved. :)

Ok guys. Problem solved :)
I attached fixed jetpipe script.
You should save it to /opt/ltsp/i386/usr/sbin, chmod 755 /opt/ltsp/i386/usr/sbin/jetpipe and make itsp-update-image

From what I can see, your code is almost identical to the current upstream one.
Only difference is additional error handling upstram.

I'm marking that bug as fix released in current ltsp.

Thanks Anton ! I've experienced similar problems - have replaced the jetpipe script in our LTSP image. Now it prints with no problem.

Thanks again. Much appreciated.
