Agenda
- More testing for network integration of ippusbxd, especially for Avahi broadcasting of IPP-over-USB printers.
- Continued working on support for driverless printing.
- Aveek Basu (Lexmark) reached out to Indian schools and found 6 students to work on the Common Printing Dialog in this Google Summer of Code. - Pranjal Bhor from last year will work on cups-filters and QPDF so that filled PDF forms get printed correctly.
- CUPS source code and bug reports are handled on GitHub now
- https://github.com/apple/cups/
- CUPS summary (Till)
- Main new point is the support for the Apple Raster format. This allows
support for driverless printing not only on IPP Everywhere printers but
also on Apple AirPrint printers.
- The Apple Raster and PWG Raster formats are very similar and Apple
AirPrint and IPP Everywhere mainly differ by using the different raster
formats. So Till did a lot of testing and added appropriate support also
to CUPS filters to extend driverless printing to AirPrint there, too.
- See also Till's "OpenPrinting News" report from January 2017.
- The "lpadmin ... -m everywhere ..." call works for both IPP Everywhere
and Apple AirPrint printers and results in a working print queue with
auto-generated PPD file in both cases.
- CUPS v2.2.2 release on 17 January 2017 (Mike)
- Fixed some issues with the Zebra ZPL printer driver (Issue
#4898)
- Fixed some issues with IPP Everywhere printer support (Issue
#4893, Issue #4909, Issue #4916, Issue #4921, Issue #4923,
Issue #4932, Issue #4933, Issue #4938)
- The rastertopwg filter could crash with certain input (Issue
#4942)
- Optimized connection usage in the IPP backend
(<rdar://problem/29547323>)
- The scheduler did not detect when an encrypted connection was
closed by the client on Linux (Issue #4901)
- The cups-lpd program did not catch all legacy usage of
ISO-8859-1 (Issue #4899)
- Fixed builds on systems without a working poll()
implementation (Issue #4905)
- Added a USB quirk rule for the Kyocera Ecosys P6026cdn (Issue
#4900)
- The scheduler no longer creates log files on startup
(<rdar://problem/28332470>)
- The ippContainsString function now uses case-insensitive
comparisons for mimeMediaType, name, and text values in
conformance with RFC 2911.
- The network backends now log the addresses that were found
for a printer (<rdar://problem/29268474>)
- Let's Encrypt certificates did not work when the hostname
contained uppercase letters (Issue #4919)
- Fixed reporting of printed pages in the web interface (Issue
#4924)
- Updated systemd config files (Issue #4935)
- Updated documentation (PR #4896)
- Updated localizations (PR #4894, PR #4895, PR #4904, PR #4908,
Issue #4946)
- Updated packaging files (Issue #4940)
- CUPS Filters summary (Till)
- Bug fixes for driverless printing support, make the process work
more consistently and assure that PPDs get generated whenever
possible.
- Allow passing through JPEG input files to driverless printers.
- CUPS Filters v1.13.4 release on 17 February 2017 (Till)
- libcupsfilters: Let PPD generator for driverless printing
not error out when there is no urf-supported or
pwg-raster-document-resolution-supported IPP attribute,
simply accept the default resolution also from the
printer-resolution-default attribute or set a default value
of 300 dpi to get a working PPD file.
- cups-browsed: Do not use deprecated names for IPP status
constants
- cups-browsed: Corrected determination whether an IPP status
is an error, to avoid "Unable to create/modify CUPS queue
(Success)" and infinite repetition of a succeeded operation
(Debian bug #852436).
- CUPS Filters v1.13.3 release on 18 January 2017 (Till)
- libcupsfilters: When auto-generating PPD files added support
for passing through JPEG input to printers which understand
JPEG. This is also done in CUPS-generated PPDs (Debian bug
#851499).

to work on the Common Printing Dialog in this Google Summer of Code.
