| 09a101d6 | 11 | <P>CUPS supports a variety of printer accounting schemes. Aside from the |
| 12 | built-in <A HREF="#QUOTAS">quota</A> and <A HREF="#PAGELOG">page logging</A> | |
| 075b444b | 13 | support, there are several third-party solutions that can be found online.</P> |

| 16 | <H2 CLASS="title"><A NAME="QUOTAS">Quota Support</A></H2> | |
| 17 | ||
| 18 | <P>CUPS supports page and size-based quotas for each printer. | |
| 19 | The quotas are tracked individually for each user, but a single set of | |
| 22c9029b | 20 | limits applies to all users for a particular printer. For example, you |
| 09a101d6 | 21 | can limit every user to 5 pages per day on an expensive printer, but |
| 22 | you cannot limit every user except Johnny.</P> | |
| 23 | ||
| 22c9029b | 24 | <P>The <CODE>job-k-limit</CODE>, <CODE>job-page-limit</CODE>, and <CODE>job-quota-period</CODE> |
| 09a101d6 | 25 | options determine whether and how quotas are enforced for a printer. |
| 26 | The <CODE>job-quota-period</CODE> option determines the time interval for | |
| 27 | quota tracking. The interval is expressed in seconds, so a day is | |
| 22c9029b | 28 | 86,400, a week is 604,800, and a month is 2,592,000 seconds. The |
| dd3fdd2c | 29 | <CODE>job-k-limit</CODE> option specifies the job size limit in kilobytes. The |
| 09a101d6 | 30 | <CODE>job-page-limit</CODE> option specifies the number of pages limit.</P> |
| 31 | ||
| 32 | <P>For quotas to be enforced, the period and at least one of the limits | |
| 33 | must be set to a non-zero value. The following options will enable | |
| 34 | weekly quotas with the given size and page count limits:</P> | |
| 35 | ||
| 36 | <PRE CLASS="command"> | |
| 37 | <KBD>/usr/sbin/lpadmin -p <I>printer</I> -o job-quota-period=604800 \ | |
| 38 | -o job-k-limit=1024 ENTER</KBD> | |
| 39 | <KBD>/usr/sbin/lpadmin -p <I>printer</I> -o job-quota-period=604800 \ | |
| 40 | -o job-page-limit=100 ENTER</KBD> | |
| 41 | </PRE> | |
| 42 | ||
| 43 | <P>Or, you can combine all three options on the same line.</P> | |
| 44 | ||
| 45 | <P>While there is no way to query the current quota state for a particular | |
| 46 | user, any application can request a list of jobs for a user and printer that | |
| 47 | can be used to easily determine that information.</P> | |
| 48 | ||

| 50 | <H2 CLASS="title"><A NAME="PAGELOG">Page Logging</A></H2> | |
| 51 | ||
| 075b444b | 52 | <P>CUPS can log every page that is printed on a system to the <VAR><A HREF="man-cupsd-logs.html">page_log</A></VAR> file. Page logging must be enabled by setting the <CODE>PageLogFormat</CODE> directive in the <VAR><A HREF="man-cupsd.conf.html">cupsd.conf</A></VAR> file and is only available for drivers that provide page accounting information, typically all PostScript and CUPS raster devices. Raw queues and queues using third-party solutions such as Foomatic generally do not have useful page accounting information available.</P> |
