====== Printserver ======
If you are in a household with several client computers that want to share a printer, you could use a Raspberry Pi or NUC to do so. However, some printjobs can be extremely slow on a Raspberry Pi due to the limited computing power for spooling large pages.

===== Server installation and configuration =====
  - Install CUPS: <code>sudo apt install cups</code>
  - After the installation go to the dicectory ''/etc/cups'' and edit the ''cupsd.conf''. Edit the following lines: <code>Listen localhost:631</code> must be <code>Listen *:631</code>
  - Look for all sections beginning with ''<Location>'' and add the following line as a last line in that section to allow printing and administration from the local network: <code>Allow @LOCAL</code>
  - On a Raspberry Pi, add the user ''pi'' to the group ''lpadmin'' so you can use this username for the web interface: <code>sudo adduser pi lpadmin</code>
  - Afterwards, restart the CUPS daemon: <code>systemctl restart cups</code>
  - Finally, go to the CUPS webinterface "Administration" tab on your server through ''<nowiki>https://Server-IP-or-Name:631/admin</nowiki>'' and check the following:
    * Share printers connected to this system
    * Allow remote administration
    * Allow users to cancel any job (not just their own)\\ This shouldn't matter much in your home network, if you are concerned you can of course leave this off.
  - Click "Change Settings" and the server is ready to go. Just add your printer(s) as needed.

===== Client configuration =====
On the client side installation and configuration is a lot easier.

  - Install the CUPS Client: <code>apt install cups-client</code>
  - Create the file ''~/.cups/client.conf'' with the following content: <code>ServerName RaspberryPi-IP-or-Name</code> It is possible that the directory ''~/.cups'' doesn't exist, just create it. If you prefer that to be a global setting, create that same file in ''/etc/cups''.
  - That's it, now you're good to go!
