- CUPS Filters principal changes (Till)
- Added long-standing missing feature of page logging/accounting into
the /var/log/cups/page_log file.
- cups-browsed: Added debug logging into a file
- cups-browsed: Fixed hang on system shutdown with systemd.
- gstoraster: Exit with error status when Ghostscript errors out or
crashes.
- Bug fixes
- Documentation fixes
- CUPS Filters v1.9.1 release plans (Till)
- foomatic-rip: Updated man page for removed page logging
facility.
- pdftops: Also added Dell to the list of manufacturers whose
printers need Poppler's PostScript to work around their
PostScript interpreter bugs (Debian bug #827040).
- CUPS Filters v1.9.0 release on 9 June 2016 (Till)
- foomatic-rip: Removed page logging via insertion of
PostScript code. This works only with Ghostscript and
PostScript input and even then it can break things or simply
not work. We do the page logging for foomatic-rip in pdftopdf
now, which is more universal and more reliable.
- sys5ippprinter: Added page logging (to /var/log/cups/page_log)
functionality.
- pdftopdf: Added functionality for logging pages in the
/var/log/cups/page_log file. Logging can also be forced or
suppressed via command line (page-logging=on/off/auto) and
page logging is also done for filters which should do but
actually do not do: foomatic-rip, gstopxl, hpps (CUPS issue
#4798, Ubuntu bug #1585380).
- pdftopdf: Whitespace and indentation clean-up.
- README: Removed the documentation of the old Poppler-based
pdftopdf filter which is not included any more.
- cups-browsed: Do not schedule failed operations for later
repetition during shutdown.
- cups-browsed: Added support for debug logging into a file
(usually /var/log/cups/cups-browsed_log, to be activated via
"-l" or "--logfile" option or via "DebugLogging file" option
in cups-browsed.conf.
- cups-browesd: Consistent use of debug_printf() in the LDAP
support.
- cups-browsed: Added "Requires=cups-service" to the
cups-browsed.service file, so that systemd keeps CUPS running
while shutting down cups-browsed on system shutdown (Ubuntu
bug #1579905).
- README: Extended pdftopdf documentation.
- README: Added documentation for the pdfAutorotate option in
pdftopdf.
- gstoraster: Treat status output of the waitpid() function
properly, to avoid gstoraster exiting with zero status when
Ghostscript exited with non-zero status or got terminated by
a signal (Bug #1354).
- README: Fixed typos. Thanks to Pranjal Bhor (bhor dot pranjal
at gmail dot com) for the patch.
- braille: Recognize application/vnd.cups-pdf-banner MIME type
and read standard input directly instead of using /dev/stdin.
- braille: Drop output of the "type" command when checking the
presence of helper utilities.
- braille: Do not send EOF twice to the braille embosser.
- cups-browsed/sys5ippprinter: Fixed documentation about the
allowed input formats for auto-created network printer queues
using sys5ippprinter, also improved NEWS entry about renaming
of sys5ippprinter (Debian bug #819665).
- Open Printing projects for 2016
- Add muPDF support to CUPS Filters
- Pranjal Bhor (from India)
- Using the lightweight MuPDF PDF interpreter allows for a
smaller and less resource-consuming printing stack on mobile
devices and appliances. Work will consist of adding a rastertops
filter, adding MuPDF support to the existing filters, and
adding a facility to flatten filled forms in PDF files to
static PDF content to assure filled in data will get printed.
- STATUS
- Nearly completed the rastertops filter
Will probably be ready before midterm (next week, 20-27 June)
- Communicating well with Till (mentor) and also with the upstream
developers of Ghostscript (for PostScript-specific questions
- Complete IPP discovery support in GTK Dialog
- Kevin Naughton Jr. (from New York)
- Find and list IPP network printers with their options without
need of a running cupsd and/or cups-browsed.
- STATUS

and also communicating with Marek Kasik, original maintainer
of the GTK print dialog

- Impact on distribution-independent drivers from Open Printing
- topic was discussed during PWG/OP Summit in April
- Till is looking into keeping up the LSB at least for Ubuntu 16.04 LTS
- but after that new ways of distribution-indpendent printer driver
packages must be found
- Approaches?
- partially static linking, not completely statically linking
- completely static linking with a replacement for libc
ACTION: Till and Ira draft new content for Open Printing website that
explains the various approaches to distribution-independent drivers
without dependencies on LSB (i.e., advantages and drawbacks) and also
describes the approach of PPD-based drivers (for legacy printers that
support a standard printer language - PDF, PostScript, PCL)
