cups-filters 1.28.14

Bug fix release to get correct PDF output when using "landscape", "orientation-requested", and/or "nopdfAutoRotate" options, and to get PCLm printing work on printers not telling their PCLM default resolution.

• pdftopdf: Correct the output when suppressing auto-rotation (option "nopdfAutoRotate"). Depending on the situation pages got cropped in the wrong orientation or de-centered.
• pdftopdf: Correct the output when the "orientation-requested" or the "landscape" option is supplied. Output could be de-centered (Issue #456), portrait-oriented pages be wrongly cropped and division of the output page into cells for N-up done in the wrong orientation.
• rastertopdf: In PCLm output mode the filter failed to generate PCLm if the printer has no "pclm-source-resolution-default" IPP attribute.

cups-filters 1.28.13

Bug fix release, for correct printing on printers which take in the paper long-edge-first and for Apple LaserWriter printers.

• pdftopdf: Fix N-up printing when paper is taken long-edge-first by the printer.
• pdftopdf: Fix cropping ("print-scaling=none" and "print-scaling=fill") when paper is taken long-edge-first by the printer (Issue #454).
• pdftops: Use Poppler for all Apple LaserWriter models (Issue #452).

cups-filters 1.28.12

Bug fix release, containing backports of many of the bugs recently fixed during the preparation of the cups-filters 2.x release. This time many page geometry bugs in the pdftopdf and imageto... filters were fixed especially with print-scaling and number-up, but also bugs in cups-browsed and in the serial backend got fixed.

• imagetoraster, imagetopdf: Fixed comparison of the image size with the page size for print-scaling=auto. The image size in pixels was compared with the page size in PostScript points (1/72 inch).
• imagetoraster, imagetopdf: Fixed the "print-scaling=none" (crop-to-fit) mode, also use crop-to-fit always when requested, do not fall back to fit-to-page when the image size differs significantly from the page size (Issue #362).
• libcupsfilters: Changed the default PPI resolution for images as input files from 128 to 200 (Pull request #446).
• implicitclass: Do not check availability of "gs" and "pdftops" executables, instead, check by the presence of "gstoraster" and "pdftoraster" filters whether we have configured cups-filters for Ghostscript and/or Poppler use.
• libcupsfilters: In the PPD generator for the driverless utility and cups-browsed add "*cupsFilter2: ..." lines for all supported driverless data formats (PDF, Apple/PWG Raster, PCLm), and add lines for legacy data formats (PCL, PostScript) only if no driverless formats available.
• libcupsfilters: Always use encryption for ipps. RFC7472 requires that 'ipps' must be used over HTTPS, but the driverless utility does not enforce encryption (Pull request #433).
• serial: Add a 10-msec sleep and at the end add a tcdrain(). For some unknown reason, every printing file need sleep a little time to make sure the serial printer receive data is right (Pull request #431).
• libcupsfilters: Fix resolver functions for DNS-SD-based URIs, to make resolve_uri() also work when DEVICE_URI env variable is set and to make ippfind_based_uri_converter() not re-direct stdin.
• pdftopdf: Set default for print-scaling to avoid "should never happem" log messages and undefined behavior.
• pdftopdf: Fix orientation-requested = 0. Consider this as "automatic selection and not as error.
• pdftopdf: Fixed all combinations of print-scaling and number-up for printers with asymmetric margins (top != bottom or left != right) and for input files containing pages with different sizes and/or orientations. Fixes backported from 2.x branch.
• pdftopdf: Add 2% tolerance for input size larger than output page when "print-scaling=auto" or "print-scaling=auto-fit" is used and too large input pages should be scaled, fitting documents not. This prevents a random-looking behavior if input and output page size seem to be equal, but in reality there are slight differences between size dimensions.

cups-filters 1.28.11

Bug fix release, containing backports of many of the bugs recently fixed during the preparation of the cups-filters 2.x release. Important is that cups-browsed's queue naming is aligned with CUPS' temporary queue naming now and several bugs affecting driverless printing are fixed.

• libcupsfilters: Let PPD generator take default ColorModel from printer (CUPS issue #277).
• Braille: In vectortopdf check inkscape version to call inkscape with the correct command line (Issue #315, Pull request #443).
• Build system: Make missing DejaVuSans.ttf non-fatal in ./configure as the font is only needed for test programs, not for actual use of cups-filters (Issue #411).
• libcupsfilters: In imagetoraster() fixed crash with SGray (Issue #435).
• cups-browsed: Naming of local queues is matched to CUPS' current naming of temporary queues (no leading or trailing underscores), to avoid duplicates in print dialogs which support CUPS' temporary queues.
• libcupsfilters: Make cupsRasterParseIPPOptions() work correctly with PPDs (Issue #436).
• libcupsfilters: Let colord_get_profile_for_device_id() not return empty file name, to avoid error messages in CUPS error_log.
• foomatic-rip: Debug message was wrongly sent to stdout and not to log (Issue #422).

cups-filters 1.28.10

Bug fix release: More reliable legacy CUPS browsing in cups-browsed, improved PDF printer sample PPDs, with borderless page sizes, eliminated unneeded dependency on DjVu font, minor fixes

• Sample PPDs: Add borderless page size definitions to Generic PDF Printer, HP Color LaserJet CM3530 MFP PDF, and Ricoh PDF Printer PPD files.
• Sample PPDs: From the PDF PPD files removed the unneeded "*cupsFilters2: ..." line. For CUPS it does not make any difference.
• libcupsfilters: Fixed pdftopdf filter to correctly support page ranges without upper limit, like "10-" (Pull request #399).
• libcupsfilters: Use wildcard tag (IPP_TAG_ZERO) search for "media-type" and "media-type-supported" in the PPD generator (Pull request #398).
• implicitclass, parallel: Added missing newlines at error messages.
• libfontembed: Removed unneeded fontembed/main.c and ttfread executable. Eliminates the dependency on DejaVuSans.ttf (Issue #386).
• gstoraster: Refactor the filter a little to clarify handling of page counts and set job-impressions for TotalPageCount in PWG-Raster header (Pull request #394).
• cups-browsed: Make NotifLeaseDuration configurable and renew after half the lease duration not 60 sec before end. The early renewal improves reliability on busy systems a lot. For easier development and debugging short durations from 300 sec on can get selected (Pull request #378).

cups-filters 1.28.9

Bug fix release, fixes backported from the master (2.x) branch.

• libcupsfilters: Silenced compiler warnings
• libcupsfilters: Removed duplicate code in the apply_filters() function.
• driverless: If there are no driverless IPP printers available let "driverless" terminate with exit code 0 and not 1, to follow CUPS' standard of backends in discovery mode terminating with 0 if there are no appropriate printers found (Issue #375).
• gstoraster, foomatic-rip: Fixed Ghostscript command line for counting pages as it took too long on PDFs from evince when printing DjVu files (Issue #354, Pull request #371, Ubuntu bug #1920730).
• cups-browsed: Renamed ldap_connect() due to conflict in new openldap (Issue #367, Pull request #370).
• pdftoraster: Free color data after processing of each page (Pull request #363).
• cups-browsed: Always save "...-default" option entries from printers.conf, regardless of presence or absense of PPD file (Pull request #359).
• cups-browsed: Start after network-online.target (Pull request #360).
• texttopdf: Set default margins when no PPD file is used (Pull request #356).

cups-filters 1.28.8

Bug fix release, to fix several different issues

• libcupsfilters: Made check whether the driverless PPD to generate should be a fax out PPD more reliable (Issue #343).
• foomatic-rip: Options in the 5th command line argument of the CUPS filter command line are separated only by white space and not by comma, also make sure that an option "none" is not considered a custom page size (Issue #348).
• implicitclass: Raise timeout for cups-browsed's answer from 20s to 60s (Pull request #346).
• libcupsfilters: In the PPD generator really give priority to Apple Raster against PDF (Issue #331).

cups-filters 1.28.7

Bug fix release to remove the support quality check from the "driverless" utility to do not break CUPS' PPD listing facility and several fixes for generating PPDs for driverless printers

• 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) timing 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 1.28.6

Bug fix release, fixing lots of memory leaks in cups-browsed, fixed cups-browsed hanging several seconds when there are local print queue with invalid DNS-SD-based URIs, several fixes on the PPD generator for IPP printers, taken from OpenPrinting's fork of CUPS, and fixing bugs on foomatic-rip

• libcupsfilters: In generated PPDs add a grayscale mode if there are only color printing modes (from OpenPrinting CUPS).
• libcupsfilters: In generated PPDs add an "OutputBin" option also if it has only one choice (OpenPrinting CUPS pull request #18).
• libcupsfilters: Generated PPDs could have an "Unknown" default InputSlot (OpenPrinting CUPS issue #44).
• cups-browsed: Removed unneeded IPP attribute additions preventing the created local queues from preserving a location or description the user assigns to them (Issue #323).
• cups-browsed: Removed all calls of the resolve_uri() function of libcupsfilters, as these are not actually needed and in case the supplied DNS-SD-based URI is not resolvable, the function gets stuck for ~5 seconds.
• cups-browsed: Fixed several memory leaks, mainly from the code to merge printer IPP attributes for clusters (Pull request #322).
• cups-browsed: Silenced compiler warning.
• foomatic-rip: Fix infinite loop and input from file on raw printing (Pull request #318).
• foomatic-rip: Remove temporary file created during pdf-to-ps conversion (Pull request #313).

cups-filters 1.28.5

Bug fix release for a quick, potential crasher correction in cups-browsed

• cups-browsed: UUID from IPP response was used after its pointer was freed by ippDelete() (Pull request #311).
