Problem installing a USB printer on a LTSP client
 

Hello,

I am using Ubuntu Studio as LTSP server and i have confiured a network printer which works fine for all the users. But, there's new HP officejet 4355 All-in one printer which has only a USB port. I have installed the recommended hplip-2.8.6.run binaries/libraries, but i am not able to setup the local printer. Coz, when i plug in the printer to the USB port on the LTSP client, the OS doesn't detect any device. I guess the USB ports can detect only drives for data storage.

Just to clarify, the local devices option is enabled on the LTSP server. If i plug in a USB drive, the client can detect it without any problems.

How do i make this work??

This isn't really my "thing", but you have zero-replies for nearly two days, so here goes:
Why do you say that?
Plug in the printer and turn it on. What is the output of lsusb ?
Nope, linux detects and configures: my mouse, camera, webcam, mobile-phone-broadband dongle, iPod and a whole lot more I expect.

Please see here (I just used a search engine):
http://www.linuxprinting.org/show_pr...355_All-in-One
for more about your printer and linux. Looks like you'll need hpijs

Thanks for the reply.

I have installed the hplip-2.8.6.run binaries/libraries, which gives me an option to install printers connected to the local USB port. I have not checked the output of lsusb, but when i did lsusb last time it gave me two ports, but there are 4 ports on the machine. I will check the link you have mentioned and get back if necessary.

Sorry for posting it again, it was by mistake. I will remove it right away.

The printer is connected to the local machine that is to the LTSP client!! Its strange, coz when the Linux OS is accessing a USB pen drive when i plug-in, how can there be a access problem. Below is a listing of USB devices in /dev directory.
usbdev1.1_ep00 usbdev1.1_ep81 usbdev2.1_ep00 usbdev2.1_ep81

I really appreciate your help and i hope there is a easier way to do this.

Hi,

Please post your lts.conf file

here a section of mine that has two usb printers connected to it

Hope it points you into the right direction.

The contents of lts.conf


# This is the default lts.conf file for ltsp 5.
# For more information about valid options please see:
# /usr/share/doc/ltsp-client/examples/lts-parameters.txt.gz
# in the client environment.
#
# Note that things like sound and local device support are
# auto-enabled if the corresponding packages are installed,
# there is no need to manually set these options anymore.
#
# **** THIS FILE SHOULD NO LONGER BE USED FROM HERE !!! ****
#
# With the introduction of the nbd/unionfs/squashfs structure
# the lts.conf file moved to the tftp root please create:
# /var/lib/tftpboot/ltsp/i386/lts.conf instead for your changes
#
# In case you want to use the lts.conf here, this still works,
# but you need to run ltsp-update-image after every change.


The contents of ltsp-client-core file - my configuration file

The IP Address in your code, is that the IP of the LTSP Client? I am need of installing a couple of USB Printers on LTSP clients.

Hi,

I stumbled onto this thread again and somehow i missed ur reply.
Did u manage to get ur printers workin?

The ip addres is that of my client.

No I Just couldn't get it working.

I have a new LTSP installation and i am still trying to install a USB printer on a LTSP client machine.

lts.conf

[default]
X_COLOR_DEPTH=16
LOCALDEV=True
SOUND=True
NBD_SWAP=True
SYSLOG_HOST=server
LDM_GUESTLOGIN = TRUE


# A Thin Client Printer
[10.10.10.105]
PRINTER_0_DEVICE=/dev/usblp0
PRINTER_0_TYPE=U
PRINTER_0_PORT=9100

Strangely, i dont find /dev/usblp0 nor /dev/usb folder on my system.
I have assigned a fixed IP mentioned above in DHCP config file.
I have loaded USBLP module also. Should i load the lsusb module in chroot?

How can i get this working?

Thanks
