Agenda

(0) IPP over USB (Till)
https://github.com/tillkamppeter/ippusbxd/commits/master

- Till is working with several printer manufacturers

- No further news/tests/changes/releases

(1) Status of Self-Certification for IPP Everywhere (Mike/Ira)
```
- See PWG News below
```

(2) Status of CUPS and CUPS Filters (Till)

- CUPS source code and bug reports are handled on GitHub now
  - https://github.com/apple/cups/

- CUPS release v2.2.1 on 3 October 2016 (Mike)
  - Added "CreateSelfSignedCerts" directive for cups-files.conf to control
    whether the scheduler automatically creates its own self-signed X.509 
    certificates for TLS connections (Issue #4876)
  - http*Connect did not handle partial failures (Issue #4870)
  - Addressed some build warnings on Linux (Issue #4881)
  - cupsHashData did not use the correct hashing algorithm 
    (<rdar://problem/28209220>)
  - Updated man pages (PR #4885)
  - Updated localizations (PR #4877, PR #4886)

- CUPS release v2.2.0 on 13 September 2016 (Mike)
  - Normalized the TLS certificate validation code and added additional 
    error messages to aid troubleshooting.
  - http*Connect did not work on Linux when cupsd was not running (Issue #4870)
  - The --no-remote-any option of cupsctl had no effect (Issue #4866)
  - http*Connect did not return early when all addresses failed (Issue #4870)

- CUPS Filters recent changes summary (Till)
  - Output correct PWG Raster when Poppler is used as PDF interpreter.
    Before, the bitmap had the unprintable margins cut off, but PWG
    Raster requires a full-page bitmap including the margins (I have
    fixed this also in Ghostscript upstream in the last few days).
  - Do page logging when the printer gets the job in PWG Raster format.
  - cups-browsed did not create a local queue when the remote CUPS queue
    name contained a dot.
  - New variables BrowseInterval and BrowseTimeout for legacy CUPS
    Browsing in cups-browsed.conf.
  - The ./configure script works also correctly on build servers and for
    cross compiling where tools needed only on run time (like
    Ghostscript) are not installed.
  - The filters now use the $PATH environment variable when calling
    utilities like Ghostscript, MuPDF,... This allows for easier 
    cross-compiling or generally easier use of build servers which do not 
    have the utilities installed.
  - Several bug fixes.

- CUPS Filters v1.11.6 release on 31 October 2016 (Till)
  - pdftops: Do not default to simply "pdftops" when calling the
    Poppler pdftops utility, as the $PATH of CUPS when running
    filters/backends starts with /usr/lib/cups/filter/ and then
    pdftops would call itself (Bug #1380).

- CUPS Filters v1.11.5 release on 28 October 2016 (Till)
  - cups-browsed: Fixed several typos in the documentation (Bug #1378).
  - gstoraster, mupdftoraster, pdftops, sys5ippprinter: Use
    execvp() and execvpe() to call programs so that the $PATH
    environment variable gets used to find the programs (Bug #1378).
  - build system: Several fixes, especially to make it work when
    cross-compiling or using a build server (Bug #1378).
  - cups-browsed: Silenced a warning.
  - cups-browsed: For remote CUPS queues with a dot in their
    name no local queue got created (Bug #1379).
  - pdftopdf: Do the page logging also for IPP Everywhere
    printers which use the PWG Raster data format as the
    ...toraster filters being the last filter then do not log.
  - gstoraster, pdftoraster: Let filters generate PWG Raster if
    the environment variable FINAL_CONTENT_TYPE is set to
    image/pwg-raster, make sure full-page bitmaps are generated
    in PWG_raster mode, and added mime conversion rules for
    direct PWG Raster output.
  - cups-browsed: Corrected checking of the PDLs of an IPP network
    printer. Now PCL 5c/e printers (not HP inkjets) should get
    recognized correctly.
  - texttopdf: Added missing NULL check to avoid a segfault when
    texttopdf does not find a suitable (monospace TTF) font.
  - foomatic-rip: Replace old manpage macro calls from
    foomatic-filters 3.0.2-20050114.
  - cups-browsed: Allow changing BrowseInterval and
    BrowseTimeout via cups-browsed.conf, as it was formerly with
    CUPS (Debian bug #794655).
  - pdftopdf: Count the actual output pages also if the
    number-up option is not used, to correctly find out whether
    we have an even or odd number of pages, even if the
    page-ranges option is used. This is needed to correctly
    decide whether for duplex printing a blank page has to be
    added (Bug #1377).

ACTION: Ira to query OP Japan mailing list:
(a) Is the OPVP filter still used by Japanese manufacturers?
(b) If yes, would OP Japan maintainers be willing to modify OPVP filter to remove dependencies on non-standard Poppler APIs?
(c) Otherwise, should OP add a Google Summer of Code 2017 project to update OPVP?
