[K12OSN] Local priner problem

Tue Mar 5 14:58:58 UTC 2013

When starting jetpipe manually on the thin client shell, you could try the -d option (debug). 
This may give you additional information as to why it's not printing...

Thanks a lot for all help, but still nothing. Let me explain my today exercise. 

The first I used Julius's advice: 
PRINTER_0_TYPE=S 
PRINTER_0_DEVICE="/dev/usb/lp0" # /dev/usblp0 is symbolic link to /dev/usb/lp0 
PRINTER_0_WRITE_ONLY=Y 

Nothing. 
telnet 192.168.1.10:9100 
connection refused. 

So, I started on thin client (shell console) jetpipe manually. 

Now telnet 192.168.1.10 9100 
connects, but still I couldn't print. 

So I added /usr/sbin/jetpipe to /etc/rc.d/rc.local. Now every time telnet 192.168.1.10 9100 connects, but the printer doesn't print. 

I changed PRINTER_0_TYPE=S with "U", still nothing. 

I installed using chroot python-daemon, still nothing. 
ps aux | grep python* 
shows that any python process isn't running. 

But very interesting - when I added this printer connected to thin client using system-config-printer on my LTSP server and I try to print test page, I can read the messages that printer is connected, next - the file sent to the printer, next "waiting for finishing printing job", and next "ready to use". But my printer didn't print anything. 

The advice with /dev/lp0 I tried too - still noting. 

When I try to add this printer on Windows computer using TCP/IP port (192.168.1.10:9100) I can see the message, that the printer is not connected (still telnet 192.168.1.10 9100 connects). 

Any other advice, please? 

Best regards, 
Radek

Yes, that would usually be the case I think.What happened to us with parallel printers is that we see no device in the /dev directory that corresponds to the printer (no /dev/lp0 or similar). So no matter what you put in PRINTER_0_DEVICE, jetpipe will complain about not finding the device and dies. 
We ended up not bothering about parallel printing and are now using serial or usb.

I think for parallel port printers you need to use 
PRINTER_0_DEVICE = "/dev/lp0" instead of "/dev/usblp0" 
PRINTER_TYPE = P instead of U or S
