This document sets out to describe how to install and configure CUPS on GNU/Linux I'll assume that you already know why you need CUPS. Configuring for a different printer shouldn't be that difficult, CUPS is super easy to use.
Praxis comes with CUPS configured as, using Avahi not Zeroconf
[ebuild U ] net-print/cups-1.3.11-r3 [1.3.11-r2] USE="-X acl avahi dbus gnutls -java jpeg -kerberos -ldap pam perl -php png ppds python -samba -slp ssl -static tiff -xinetd -zeroconf"
We have minimal bindings and exclude Samba because Windows folks should be printing via IPP, not Samba=>CUPS We are using Avahi and not Zeroconf, DBUS must be included.
For printing from Windows through Samba update the MIME configurations. Firstly mime.types and mime.convs need to be edited as follows, the lines are commented out near the bottom of each file.
/etc/cups/mime.convsapplication/octet-stream application/vnd.cups-raw 0 - #
Configure the CUPS system to allow local network sharing, remote administration, and printing over IPP to your local subnet. This is wide open to your LAN.
ServerName fqdn.domain.tld Listen 0.0.0.0:631 Browsing On BrowseOrder allow,deny BrowseAllow all BrowseLocalProtocols CUPS BrowseAddress @LOCAL <Location /> Order allow,deny Allow localhost Allow from @LOCAL </Location> <Location /admin> Order allow,deny Allow localhost Allow from @LOCAL </Location>
Now check the CUPS web-interface:
The CUPS interface is easy, just Add Printer and follow the wizard.
426 Upgrade Required
The CUPS system may require encrypted communications for some of the processes. This warning can be resolved in one of two ways: a) encrypt the communications or b) disable the requirement.
Encrypting with OpenSSL
Create an SSL certificate
openssl req -new -x509 \ -keyout /etc/cups/ssl/server.key \ -out /etc/cups/ssl/server.crt -days 3650 -nodes
Then update cups.conf to include the following, this example shows the defaults
DefaultEncryption Required ServerCertificate /etc/cups/ssl/server.crt
It should be noted that at this time CUPS (<=1.5) validate or revoke certificates, so this configuration does not provide the full faith and trust which SSL/TLS should provide. See the CUPS Encryption Issues for more information.
Or b) disable the security requirement (shame on you) - update /etc/cups/cupsd.conf to include the following:
Installing Printer Drivers
Out of the box CUPS provides many printer drivers in the form of PPD files, some distribuions have additional driver set packages such as.
emerge net-print/foomatic-db-ppds net-print/foomatic-filters-ppds # or apt-get install foomatic-filters hp-ppd hpijs-ppds openprinting-ppds openprinting-ppds-extra
Printing from Windows
To print from Windows to the CUPS server we use IPP directly. When creating a new Windows printer simply point the system to one of the following. There are variances depending on your Windows versions, XP+SP2 vs SP3 vs Windows 7, &c. This will work in Mac OS X too.
