<P>CUPS 1.1 includes many new features from the 1.0.x releases.


<H3><CODE>imagetoraster</CODE>, <CODE>imagetops</CODE></H3>

<P>The image file filters have been upgraded to support conversion of
Microsoft Bitmap ("BMP") and Alias PIX files.


<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>The <CODE>pstoraster</CODE> filter has been integrated with GNU
GhostScript 5.50. The new RIP supports most Level 3 PostScript language


<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.

<H2>User-Defined Printers and Options</H2>

<P>The new <CODE>lpoptions</CODE> command allows users to configure default
document options and create additional "instances" of existing printers,
each with unique options.

<P>The <CODE>lp</CODE>, <CODE>lpr</CODE>, and <CODE>lpstat</CODE> commands
have been upgraded to use this option and printer instance information


<P>CUPS 1.1 includes two new daemons that provide enhanced network printing


<P>The <CODE>cups-lpd</CODE> daemon provides support for clients using the
Line Printer Daemon protocol.


<P>The <CODE>cups-polld</CODE> daemon provides remote polling services for
the scheduler.


<P>CUPS 1.1 includes several new printing commands.


<P>The <CODE>lpoptions</CODE> command provides user-defined printers and


<P>The <CODE>lpmove</CODE> command moves a print job to a new destination.


<P>The <CODE>lpinfo</CODE> command lists the available PPD files or devices.

<H2>IPP Implementation</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>Further information on the CUPS implementation of IPP can be found
in CUPS-IPP-1.1.


<P>CUPS 1.1 includes many changes from the 1.0.x releases.

<H2>Directory Structure</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.

<CAPTION>Table 1: Directory structure changes from CUPS 1.0.x to 1.1.x.</CAPTION>

	<TD>Request files</TD>

<H2>IPP Implementation</H2>

<P>CUPS 1.1 is based on version 1.1 of the Internet Printing Protocol.

<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>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>

<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>Further information on the CUPS implementation of IPP can be found
in CUPS-IPP-1.1.
