| ===CUPS===

| | | [[Category:Draft documentation]] |
| The version of cups provided with Fedora is cups-1.4 and following are the features in general, Though there are about number of changes <br>
| | [[Category:Documentation beats]] |
| | |
| {{admon/note|note|Below document provides most used , and most noticeable changes}}
| |
| | |
| ====Web-Interface====
| |
| | |
| *The web-interface has been given a new look , using php-cgi and not php.
| |
| * THESE ARE TWO SEPARATE THINGS: THE PHP-CGI SWITCH IS JUST A SMALL BUG FIX - Tim
| |
| *The new interface provides more improvements to add and modify printer configuration
| |
| *The Administration page provides more advanced operations like share, unshare, provides list of backends to choose from
| |
| * THE ADVANCED OPTIONS ARE CHOICE OF PROTOCOLS FOR SHARING, MAX CLIENTS, JOB HISTORY ETC - Tim
| |
| | |
| ====IPP Support====
| |
| *CUPS now conforms to the draft IPP/2.0 and IPP/2.1 specifications
| |
| *CUPS supports the operation of downloading of files from print job using the "CUPS-Get-Document Operation"
| |
| *The scheduler and backend discovery interface support a device-location attribute where we can specify the location of the printer
| |
| *Support of hold jobs and releasing of jobs on hold
| |
| * THIS IS NOT NEW
| |
| | |
| ====Networking====
| |
| * CUPS now uses "Bonjour (DNS-SD)" providing mDNS(multicast DNS) which supports Bonjour-based printer discovery
| |
| | |
| ====Scheduler====
| |
| | |
| *Better Access control by providing support for adding multiple addresses in Allow and Deny lines, and now returns HTTP 403 (forbidden)<br>
| |
| for user who authenticates successfully , but doesn't have access to perform the operation
| |
| *Scheduler now supports an AccessLogLevel directive to control what is logged in the access_log file. There are 3 levels
| |
| | |
| config; Log when printers and classes are added, deleted, or modified and when configuration files are accessed or updated.
| |
| actions; Log when print jobs are submitted, held, released, modified, or canceled, and any of the conditions for config.
| |
| all; Log all requests.
| |
| The default access log level is actions.
| |
| | |
| *the default LogLevel is now "warn" instead of "info"
| |
| *the scheduler now supports a DefaultPaperSize directive to override the default paper size defined by the locale or libpaper configuration
| |
| *Scheduler now supports ErrorPolicy that can be defined in printers.conf, and now supports retry-current-job policy, that retries the current job immediately
| |
| * ERRORPOLICY WAS IN 1.2, ONLY RETRY-CURRENT-JOB IS NEW - Tim
| |
| *the scheduler now sets more PAM attributes to better support third-party authentication schemes.
| |
| *scheduler now coalesces configuration and state file changes to reduce the amount of disk activity and caches printer attributes to further reduce startup time.
| |
| *scheduler now starts the notifier for RSS subscriptions after creation so the feed is available immediately.
| |
| | |
| ====Printer Drivers====
| |
| *USB printer support; the usb backend now uses libusb when available to allow it to better work with third-party scanning and printing solutions.
| |
| * NO, WE HAVEN'T ENABLED THAT IN FEDORA - Tim
| |
| *the cupsPJLDisplay PPD attribute controls the PJL commands used to display the current user and job on the printer.
| |
| *new generic PostScript and PCL drivers provide improved support for laser printers, the CUPS DDK drivers offer support for many HP DesignJet printers<br>
| |
| and new label drivers offer support for Seiko and Tharo label printers.
| |
| * A new CUPS command file filter for PostScript printers provides auto-configuration, self-test page, and status and supply level reporting functions.
| |
| *The CUPS DDK is now a standard part of CUPS.
| |
| | |
| ====Filters====
| |
| *the standard image filters now support image files larger than 2GB.
| |
| *the bundled banner ("job-sheets") pages are now generated using a new banner filter provides easier customization and better support for UTF-8 text.
| |
| *the pdftops filter has been replaced with a wrapper program that runs the Xpdf, poppler, or Ghostscript PDF to PostScript utilities.
| |
| | |
| ===system-config-printer===
| |
| | |
| In this release, system-config-printer uses PolicyKit to control access to restricted CUPS functionality.
| |
| The following functions are controlled via PolicyKit policies currently:
| |
| * add/remove/edit local printers
| |
| * add/remove/edit remote printers
| |
| * add/remove/edit classes
| |
