 This software version description document provides release information
 for the Common UNIX Printing System (&quot;CUPS&quot;) Version 1.1.
<H2><A NAME="1_2">1.2 System Overview</A></H2>
<P>CUPS provides a portable printing layer for UNIX&reg;-based operating
 systems. It has been developed by<A HREF=""> Easy
 Software Products</A> to promote a standard printing solution for all
 UNIX vendors and users. CUPS provides the System V and Berkeley
 command-line interfaces.</P>
<P>CUPS uses the Internet Printing Protocol (&quot;IPP&quot;) as the basis for
 managing print jobs and queues. The Line Printer Daemon (&quot;LPD&quot;) Server
 Message Block (&quot;SMB&quot;), and AppSocket (a.k.a. JetDirect) protocols are
 also supported with reduced functionality. CUPS adds network printer
 browsing and PostScript Printer Description (&quot;PPD&quot;) based printing
 options to support real-world printing under UNIX.</P>
<P>CUPS also includes a customized version of GNU Ghostscript (currently
 based off GNU Ghostscript 5.50) and an image file RIP that are used to
 support non-PostScript printers. Sample drivers for HP and EPSON
 printers are included that use these filters.</P>

<H1><A NAME="3">3 Additions</A></H1>
<P>CUPS 1.1 includes many new features from the 1.0.x releases.</P>
<H2><A NAME="3_1">3.1 Filters</A></H2>
<H3><A NAME="3_1_1">3.1.1 <CODE>imagetoraster</CODE>, <CODE>imagetops</CODE>
<P>The image file filters have been upgraded to support conversion of
 Microsoft Bitmap (&quot;BMP&quot;) and Alias PIX files.</P>
<H3><A NAME="3_1_2">3.1.2 pdftops</A></H3>
<P>A new pdftops filter has been developed that is based on the
 excellent Xpdf 0.90 software from Derek B. Noonburg. The new filter is
 faster, smaller, and considerably more reliable than the
 Ghostscript-based filter in CUPS 1.0.</P>
<H3><A NAME="3_1_3">3.1.3 pstoraster</A></H3>
<P>The <CODE>pstoraster</CODE> filter has been integrated with GNU
 GhostScript 5.50. The new RIP supports most Level 3 PostScript language
<H3><A NAME="3_1_4">3.1.4 rastertoepson</A></H3>
<P>The new <CODE>rastertoepson</CODE> filter supports EPSON printers
 using the ESC/P or ESC/P2 command sets. PPDs are supplied for 9-pin,
 24-pin, Stylus Color, and Stylus Photo printers.</P>
<H2><A NAME="3_2">3.2 User-Defined Printers and Options</A></H2>
<P>The new <CODE>lpoptions</CODE> command allows users to configure
 default document options and create additional &quot;instances&quot; of existing
 printers, each with unique options.</P>
<P>The <CODE>lp</CODE>, <CODE>lpr</CODE>, and <CODE>lpstat</CODE>
 commands have been upgraded to use this option and printer instance
 information automatically.</P>
<H2><A NAME="3_3">3.3 Daemons</A></H2>
<P>CUPS 1.1 includes two new daemons that provide enhanced network
 printing support.</P>
<H3><A NAME="3_3_1">3.3.1 cups-lpd</A></H3>
<P>The <CODE>cups-lpd</CODE> daemon provides support for clients using
 the Line Printer Daemon protocol.</P>
<H3><A NAME="3_3_2">3.3.2 cups-polld</A></H3>
<P>The <CODE>cups-polld</CODE> daemon provides remote polling services
 for the scheduler.</P>
<H2><A NAME="3_4">3.4 Commands</A></H2>
<P>CUPS 1.1 includes several new printing commands.</P>
<H3><A NAME="3_4_1">3.4.1 lpoptions</A></H3>
<P>The <CODE>lpoptions</CODE> command provides user-defined printers and
<H3><A NAME="3_4_2">3.4.2 lpmove</A></H3>
<P>The <CODE>lpmove</CODE> command moves a print job to a new
<H3><A NAME="3_4_3">3.4.3 lpinfo</A></H3>
<P>The <CODE>lpinfo</CODE> command lists the available PPD files or
<H2><A NAME="3_5">3.5 IPP Implementation</A></H2>
<P>CUPS 1.1 adds support for the <CODE>set-job-attributes</CODE>
 extension operation as well as two new CUPS-specific extension
 operations to determine which devices and printer drivers are available
 on the system.</P>
<P>Further information on the CUPS implementation of IPP can be found in
<H1><A NAME="4">4 Changes</A></H1>
<P>CUPS 1.1 includes many changes from the 1.0.x releases.</P>
<H2><A NAME="4_1">4.1 Directory Structure</A></H2>
<P>The directory structure in CUPS 1.1 has been modified to conform to
 the Filesystem Hierarchy Standard, 2.0. The following table describes
 the new file locations.

<H2><A NAME="4_2">4.2 IPP Implementation</A></H2>
<P>CUPS 1.1 is based on version 1.1 of the Internet Printing Protocol.</P>
<P>The new scheduler supports the <CODE>create-job</CODE> and <CODE>
send-document</CODE> operations. In addition, the <CODE>job-sheets</CODE>
, <CODE>job-sheets-default</CODE>, and <CODE>job-sheets-supported</CODE>
 attributes are now supported for banner pages.</P>
<P>The <CODE>CUPS-get-printers</CODE> and <CODE>CUPS-get-classes</CODE>
 operations have been upgraded to support limited filtering based upon
 the <CODE>printer-type</CODE>, <CODE>printer-location</CODE>, <CODE>
printer-info</CODE>, and <CODE>printer-make-and-model</CODE> attributes.</P>
<P>The <CODE>CUPS-add-printer</CODE> operation now supports the <CODE>
ppd-name</CODE> attribute to specify a locally-available PPD file rather
 than sending the PPD file from the client with the request.</P>
