<H1 CLASS="title">printers.conf</H1>

<P>The CUPS scheduler (cupsd) uses the
<VAR>/etc/cups/printers.conf</VAR> file to store the list of
available printers. This file contains only locally defined
printers, not remote printers that are created automatically via
browsing. Each directive is listed on a line by itself followed
by its value. Comments are introduced using the number sign ("#")
character at the beginning of a line.</P>

<P>While the printer configuration file consists of plain text
and can be modified using your favorite text editor, you should
normally use the <A HREF="man-lpadmin.html">lpadmin(8)</A>
command, web interface, or any of the available GUIs to manage
your printers instead. If you do choose to edit this file
manually, you will need to restart the scheduler to make them
active.</P>
