- PAPPL v1.0.1 release on 12 January 2021
- Michael Sweet has now issued a first bug fix update of PAPPL, version 1.0.1.
- Many bug fixes are resulting from Coverity and also from Till's further development
of the PostScript Printer Application.
- See also the currently open and closed issues of PAPPL.
- Didier Raboud, printing maintainer at Debian, is already starting on packaging PAPPL.
- PAPPL v1.0.1 release on 12 January 2021 (Mike Sweet)
- Documentation updates (Issue #105)
- The `papplSystemLoadState` function did not load vendor attribute defaults correctly
(Issue #103)
- Vendor options without "xxx-supported" attributes are no longer shown on the printing
defaults page (Issue #104)
- Added support for Windows 10/Mopria clients that incorrectly convert the printer
resource path to lowercase (Issue #106)
- The 'papplSystemLoadState' function now calls the printer driver's status callback
after loading the printer's attributes (Issue #107)
- Added additional error handling for memory allocations throughout the library
(Issue #113)
- Fixed an issue with validation of custom media sizes (Issue #120)
- Partially-discovered SNMP printers would cause a crash (Issue #121)
- The "copies-supported" attribute was not report correctly.
- Job operations that targeted a non-existent job yielded the wrong status code.
- Printing a test page from the web interface did not trigger a reload to update the
printer and job state.
- The TLS web page was hardcoded to use "/etc/cups" for the CUPS server root.
- Fixed file output when the job name contains a '/'.
- Updated 1-bit driver output to support "photo" dither array for high print quality.
- PAPPL now (re)creates the spool directory as needed.
- Coverity: Added missing NULL checks.
- Coverity: Fixed file descriptor leaks.
- Coverity: Fixed some locking issues.
- Coverity: Fixed printer-darkness-configured bug in 'papplSystemSaveState'.
- Coverity: Fixed an error handling bug in the file printing code for the PWG test driver.
- Coverity: Removed dead code.
- PAPPL v1.0.2 planned changes (Mike Sweet)
- The 'papplSystemSetVersions' function now allows changes while the system is running
(Issue #123)
- The 'papplPrinterSetDriverDefaults' function did not validate the defaults against the
actual driver data.
- The IPP interface no longer allows the Create-Printer operation for single queue
applications.
- PAPPL v1.1b1 planned changes (Mike Sweet)
- Added 'PAPPL_SOPTIONS_NO_TLS' option to disable TLS support.
- Progress report
- The devlopment of the PostScript Printer Application is going on and has driven the
development of PAPPL forward.
- The PostScript Printer Application got several new featrures:
- Extra per-printer web interface page "Device Settings" for configuration of which
optional hardware add-ons are actually installed ("Installable Options" group in
the PPD files). The user selects which add-ons (extra trays, duplex unit, finishers,
...) are installed and the options and choices on the "Printing Defaults" page and
also the capabilities reported as response to a get-printer-attributes IPP request
from a client get appropriately adapted.
- Polling add-on setup and option defaults from the printer, triggered by buttons on
the "Device Settings" web interface page.
- New "Add PPDs" web interface page for the user to add extra PPD files to the Printer
Application, to use PostScript printers not supported by the already included PPDs.
Especially important when the PPD for a printer is not available under a free license.
- Support for collated copies (PDF or PostScript input only).
- Support for custom page sizes (but currently the size can only be set in inches).
- Made "Identify Printer" work, simply by sending a zero-page job with a certain
delay between beginning and end, to make the printer light up its display and make
noise (and perhaps also show job info on the display).
- Next steps will be:
- When auto-selecting driver prefer user-added PPDs (the user added them because he
wants to use them) and also prefer PPDs in the system’s language or at least in
English.
- Display results of PPD upload: Errors, warnings, successful uploads, issue a warning
also for PPDs with *cupsFilter(2): ... lines.
- Display all user-added PPD files with checkboxes for deleting them.
- Ignore PPD options which do not have PostScript or PJL code snippets for the option
choices.
- With appropriate features added to PAPPL we will be able to also add the following:
- Make Snap fire up Printer Application automatically as daemon and Printer
Application set up USB printers automatically when they get connected (needs support
in PAPPL.
- Human-readable strings for vendor options. Needs support in PAPPL.
- Ink level check via ps_status() function. Needs support in PAPPL.
- Once having these features implemented, the PostScript Printer Application is complete
so far.
- As other retro-fitting Printer Applications also use most of what we have in the
PostScript Printer Application now (as PPDs are used) Till is thinking about renaming
the "ps-printer-app" project into "retro-fit-printer-app", and adding conditional
compiling to activate and de-activate the appropriate pieces of code for the actual
Printer Applications: PostScript, Foomatic, Ricoh, HPLIP, ... and create appropriately
named projects (like "ps-printer-app") on the GitHub only for the snapping and putting
into the Snap Store.

- Current release is OP CUPS v2.3.3op1 on 27 November 2020
- This release already made it into Debian and Ubuntu.
- Fedora/Red Hat is using the OpenPrinting fork of CUPS, too, and we already have
some contributions from Zdenek Dohnal from Red Hat, meaning that the patches of the
different distributions get merged in the fork.

- CUPS Filters Summary (Till)
- Current release is v1.28.7 on 7 January 2021
- Bug fix release to remove the support quality check from the "driverless" utility
to not break CUPS' PPD listing facility and several fixes for generating PPDs for
driverless printers
- On the way towards 2.0.0 and driven by the further development of the PostScript
Printer Application Till has added the following new feature:
- Let the filter functions not load the PPD and not mark options in the PPD files to
make them better usable with Printer Applications and to avoid race conditions in
filter chains.
- Important bug fixes, applied to both 1.x and 2.x are
- The driverless utility does not check the printers for driverless support quality
any more. Each printer got polled with up to 3 get-printer-attributes IPP requests
and this takes significant time, especially when there are many printers, making
CUPS timing out and do not show any available driver at all.
- In the PPD generator for setting up driverless IPP printers with CUPS prefer Apple
Raster instead of PDF due to compatibility problems with some printers.
- CUPS Filters release v1.28.7 on 7 January 2021 (Till)
- driverless: Removed the support quality check from Pull request #235 as it takes
significant time for each printer being listed, making cups-driverd ('lpinfo -m')
time out when there are many printers (OpenPrinting CUPS issue #65).
- libcupsfilters: In the PPD generator give priority to Apple Raster against PDF
(Issue #331).
- libcupsfilters: Added NULL check when removing ".Borderless" suffixes from page
size names (Issue #314, Pull request #328).
- libcupsfilters: In the cupsRasterParseIPPOptions() map the color spaces the same way
as in the PPD generator (Issue #326, Pull request #327).
- libcupsfilters: Fixed addition of grayscale mode in generated PPD files, to avoid
duplicate entries (OpenPrinting CUPS issue #59).
- CUPS Filters release v2.0.0 planned changes (Till)
- Build system: Add files in gitignore that are generated by "autogen.sh", "configure",
and "make" (Pull request #336).
- implicitclass: Added "#include <signal.h>" (Issue #335).
- libppd: Removed versioning.h and the macros defined in this file (Issue #334).
- driverless: Removed the support quality check from Pull request #235 as it takes
significant time for each printer being listed, making cups-driverd ('lpinfo -m')
time out when there are many printers (OpenPrinting CUPS issue #65).
- libcupsfilters: Let the filter functions not load the PPD and not mark options in the
PPD files to make them better usable with Printer Applications and to avoid race
conditions in filter chains. To keep the behavior of CUPS filters, changed the
filterCUPSWrapper() function appropriately.
- libcupsfilters, libppd: In the PPD generators give priority to Apple Raster against
PDF (Issue #331).
- GSoC 2021
- The time window for the mentoring organizations to apply will be 29 January to
19 February 2021. See also the complete timeline. We will again apply for the
Linux Foundation as a mentoring organization, as in the previous years, OpenPrinting
being one of the sub groups.
- We are still looking for project ideas to get a good number lined up before applying.
- As mentioned already in October student projects will only be half the time (6 weeks).
So this has to be taken into account and larger projects we should consider running
under the Linux Foundation Mentoring Program instead of GSoC.
