NethServer Version: 7.3 final Module: cups
On the other computers can not print to a printer connected to the server.
/var/log/cups/error_log on server: E [31/Jan/2017:20:52:49 +0300] Returning HTTP Forbidden for Get-Printer-Attributes (ipp://192.168.0.1:631/printers/HP_LaserJet_1320) from 192.168.0.30 E [31/Jan/2017:21:14:55 +0300] Returning HTTP Forbidden for Get-Printer-Attributes (https://192.168.0.1:631/printers/HP_LaserJet_1320) from 192.168.0.30 E [31/Jan/2017:21:20:08 +0300] Returning HTTP Forbidden for Get-Printer-Attributes (http://192.168.0.1:631/printers/HP_LaserJet_1320) from 192.168.0.30
The test page is printed from the server properly.
Someone struggling with this error?
I haven’t had time to spin up a vm of NS to set up a print server, but in the past on an ubuntu basic print server this was caused where the user you authenticated with when you added the printer to the client pc isn’t allowed to print… I think… You should be able to play with the cups config file /etc/cups.cupsd.conf and add Allow All to the first option in the Policy Authentication section. I think that deals with the permissions you are having issues with.
There are a lot of different things you can change in the config file, and its fairly intuitive. I hope this helps. If this doesn’t get you in the right direction let me know and I’ll dig up one of my old print servers in storage and copy the config for you to compare with. I hope this helps.

I also have never had a problem with CUPS. Until then stood ClearOS - everything worked. On other systems SLES and openSUSE - there, too, everything works, but there’s some ambush on level ground.
In my /etc/cups/cupsd.conf:
ServerAdmin admin@iv.lan
LogLevel warn
MaxLogSize 1m
Browsing On
BrowseOrder allow,deny
BrowseAllow all
BrowseLocalProtocols CUPS dnssd
Do, but for some reason it happened - do not understand (I originally did not climb at all configs and set up through the web interface).
The cupsd.conf in “Limit All” section has been registered “Deny From All” and “Allow From 127.0.0.1”.
< Limit All>
Order deny,allow
Deny From All
Allow From 127.0.0.1
< /Limit>
Ah ah ah! Where does it come from - is not clear. I removed the print-server module, to reinstall a package cups, install again print-server module, take the default configuration and reconfigure. I check that the section would “Limit All” looked like.
cat /etc/e-smith/templates-custom/etc/cups/cupsd.conf/80PolicyDefault

I believe that the lines are commented out, I should not be. The same server, rather than the usual computer. Task Server to give access to the printer, and then for some reason, registers can be accessed only with localhost.
upd: I also believe that when you install CUPS must be installed: gutenprint-cups, cups-ipptool, cups-lpd.
I set them manually.
So I and configure through a Web interface, only the changes in this section of the “Limit All” for some reason did not apply! Fixed hands - worked, but the next time some updating I got back to the school of the “Limit All” section. And no longer print. How do you imagine this kind of work in production? Updated system - all printers have fallen off! Or after each update to check whether all the printers print a test page? If I’m going to allow this, I went to look for another job.
And for trusted networks have a firewall, which indicates that the port 631 only for the green network.
I am wrong?
I just had the exact same issue in my fresh NS7 final install. I would like to +1 on a permanent fix for this.
I run the NS as a central print server at home (among other things), because I only have one printer and several clients. And unplugging and replugging is a hassle.
