Hi dears,
I've migrated my CUPS working configuration to the Chroot image by copying
the /etc/cups directory to the target LTSP chroot image and the printers
appears in the LTSP clients GUI without any problem BUT whenever i try to
print a document i get an error message saying " Filter Failed " and the
job stops !

I've verified that the " foomatic-filters " are installed and still get the
same error...any help to solve this issue please and thanks in advance.

1) Set up all your printers on your server.
Then go to the printers control panel (system-config-printer) and select
Server => Settings => [v] Publish shared printers connected to this system.

2) The stock Ubuntu LTSP version is quite broken and old, it won't work.
Use a very recent LTSP version, e.g. LTSP 5.5.5 from the Greek schools PPA:
# add-apt-repository ppa:ts.sch.gr
# apt-get update
# apt-get dist-upgrade
both in the server and in the chroot

3) Don't do anything in lts.conf nor in the chroot cups folder.
Both thin and fat clients will automatically use
CUPS_SERVER=<server_ip>
and will see all the server's printers without any other configuration,
without having to add drivers etc.

I also had problems to print from a LTSP-PNP fat-client (version
5.5.5-1~bpo8+1).
It turns out that both server and client try to share the same printer ...

I've been able to solve this problem as follows:
1.) Make sure that you are able to use the printer form the server.
2.) On the server: Disable (within CUPS) sharing connected printers
3.) Update your image (or built your client and/or copy /etc/cups)
2.) On the server: Enable (within CUPS) sharing connected printers
5.) Boot and print from the client

Thank u all...the issue has been solved by using #chmod -R 777 cups it was
a permission issue with the configuration files causes cups to trigger
message filter errors...but again solved with fixing the cups folder
permissions...thanks gain...

A word of caution: "chmod -R 777" is almost certainly too permissive,
and will likely introduce security issues...

Most likely something just needs read permissions on a certain file...

Yes I know that only a certain file need the permission but to me it is not
a big deal because I'm the server administrator and all what i care about
is solving the issue and now I'm happy 😁

Hello,

This is a question for Alkis based on your response in this thread.
You mentioned that the stock Ubuntu LTSP version is quite broken and
old. A recent version can be added from the Greek school's PPA. If
someone is running Edubuntu (version 14.04.2) would you recommend that
PPA also?

Thank you very much!
Joseph

Hi,

all Ubuntu flavours (Ubuntu, Edubuntu, Kubuntu, Xubuntu, Lubuntu etc)
are using the same repositories, so they have the same LTSP versions.

So yup I recommend the Greek schools PPA for all Ubuntu flavors, as it's
where we're releasing newer LTSP and LDM versions that fix a lot of issues.

I wonder if you have really solved the problem.
in my experience changing printing permissions will be a disaster.
