The Common UNIX Printing System™, or CUPS, is the software you use to print from applications like the web browser you are using to read this page. It converts the page descriptions produced by your application (put a paragraph here, draw a line there, and so forth) into something your printer can understand and then sends the information to the printer for printing.

Now, since every printer manufacturer does things differently, printing can be very complicated. CUPS does its best to hide this from you and your application so that you can concentrate on printing and less on how to print. Generally, the only time you need to know anything about your printer is when you use it for the first time, and even then CUPS can often figure things out on its own.

Install CUPS printer server in Debian

apt-get install cupsys cupsys-driver-gutenprint foomatic-db-gutenprint foomatic-filters fontconfig libtiff4 libfreetype6

NOTE: If your network use DHCP it’s a good idea to set up your server to use static IP. I will use as 172.20.22.74 for the server and 172.20.22.150 for administration workstation.

Configure CUPS

Default configuration file located at /etc/cups/cupsd.conf in this file you need to configure the following sections to make it work.

First, check the encryption setting and change
# Default authentication type, when authentication is required…

DefaultAuthType Basic

to

DefaultAuthType Basic
DefaultEncryption IfRequested

Then we need to tell it to listen for the server change
# Only listen for connections from the local machine.

Listen localhost:631
Listen /var/run/cups/cups.sock

to

Listen localhost:631
Listen 172.20.22.74
Listen /var/run/cups/cups.sock

We need it to be visible to the entire network
# Show shared printers on the local network.

Browsing On
BrowseOrder allow,deny
BrowseAllow @LOCAL

what machines that may access the server change

Restrict access to the server…

<code><Location/>
Order allow,deny
Allow localhost
</Location>

to

<Location/>
Order allow,deny
Allow localhost
Allow 172.20.22.*
</Location>

And the same for the configuration files change
# Restrict access to configuration files…

<Location /admin/conf>
AuthType Basic
Require user @SYSTEM
Order allow,deny
Allow localhost
</Location>

to

<Location /admin/conf>
AuthType Basic
Require user @SYSTEM
Order allow,deny
Allow localhost
Allow 172.20.22.150
</Location>

Other configuration I left default one so need to change anything.

Now you need to restart CUPS using the following command
/etc/init.d/cupsys restart

You should now be able to connect to the CUPS web interface from the administrator workstation (IP 172.20.22.150 in this example) by pointing your web browser at http://172.20.22.74:631/.

Setting up the CUPS clients

The CUPS clients are easy to set up and the config is identical on all machines.You need to install the following packages for client

apt-get install cupsys cupsys-client

Configuring CUPS Client

You need to create /etc/cups/client.conf as root
touch /etc/cups/client.conf

Now you need to edit the /etc/cups/client.conf file
vi /etc/cups/client.conf
Enter the following information the server IP and the encryption requirement

# Servername
ServerName 172.20.22.74
# Encryption
Encryption IfRequested

Save the file, then restart the client
/etc/init.d/cupsys restart

/etc/cups/cupsd.conf

Troubleshooting

In case CUPS stop printing, check following:

Show current print queue: lpq

Show printer status: lpc status all / lpstat -a / lpstat -a

Remove all documents from queue: lprm -

Send test document to printer: lpr test.txt

Stop CUPS daemon: /etc/init.d/cups stop

Check CUPS configuration, if there is something like following, comment those lines:

#State Stopped
#StateMessage /usr/lib/cups/filter/foomatic-rip failed
#Reason paused

Start CUPS daemon: /etc/init.d/cups start
