Setting up CUPS clients
 
Hello,

I maintain a small cluster and I am trying to get all print jobs to go through the server instead of each client connected to the printer.

I have my server setup and I can run lpstat -v" and get

device for color405: ipp://128.193.96.74:631/printers/color405
device for EPSON_Stylus_Photo_R380: ipp://128.193.96.7:631/printers/EPSON_Stylus_Photo_R380
device for HP_Deskjet_F4400_series: ipp://128.193.96.7:631/printers/HP_Deskjet_F4400_series
device for Weniger303a: ipp://128.193.96.74:631/printers/Weniger303a
device for Weniger303a-Color: ipp://128.193.96.74:631/printers/Weniger303a-Color
device for Weniger412: ipp://128.193.96.74:631/printers/Weniger412
device for wngr412: socket://128.193.96.33
device for wngr497: dnssd://WNGR497-PRN2._printer._tcp.local/

The bottom two are the printers that are ran through the server.

I run "lpstat -r" and get

scheduler is running

Where I am confused is setting up the cups.conf file. The IP addresses I am connecting to are 128.193.97.x where x=1 to 37. On the server, I added

Listen *:631

and under <Location /> I added

Allow 128.193.97.0/255.255.255.0

On the client, in the /etc/cups/client.conf file I added the following

NameServer 128.193.97.2

I restart cups on both systems. Then on the client I go to
Desktop--->Administration--->Printing and it fails.

I am checking to see if I did anything wrong. Thanks!

Hi,

Just to make sure, what's the subnet mask on the server? All printers seem to be in the range 128.193.96.X so I assume the server is also in that range. Depending on the subnet mask set on the server your clients might not be able to connect.

Kind regards,

Eric

I found out that when I setup the printers, I forgot to select "to share the printers connected to the system".

Now I get 4 different printers from other cups servers that I do not control. How do I tell a client machine to only look at my cups server. Here is my cupsd.conf file if needed.
