title: 'Restrict Printer Sharing'
description: |-
By default, Samba utilizes the CUPS printing service to enable
printer sharing with Microsoft Windows workstations. If there are no printers
on the local system, or if printer sharing with Microsoft Windows is not
required, disable the printer sharing capability by commenting out the
following lines, found in <tt>/etc/samba/smb.conf</tt>:
<pre>[global]
load printers = yes
cups options = raw
[printers]
comment = All Printers
path = /usr/spool/samba
browseable = no
guest ok = no
writable = no
printable = yes</pre>
There may be other options present, but these are the only options enabled and
uncommented by default. Removing the <tt>[printers]</tt> share should be enough
for most users. If the Samba printer sharing capability is needed, consider
disabling the Samba network browsing capability or restricting access to a
particular set of users or network addresses. Set the <tt>valid users</tt>
parameter to a small subset of users or restrict it to a particular group of
users with the shorthand <tt>@</tt>. Separate each user or group of users with
a space. For example, under the <tt>[printers]</tt> share:
<pre>[printers]
valid users = user @printerusers</pre>
