This release fixes all known issues in the v1.1 tools and have been tested by myself and three other PWG members. Changes include:

  • Added support for running the self-certification tools non-interactively with the “make test” command (Issue #5656, Issue #6262)
  • The `ippevesubmit` program did not validate the correct number of tests for the document results (Issue #7171)
  • The DNS-SD TLS key test was incorrectly specified (Issue #7272)
  • The `ippevesubmit` program now validates and converts product web page URLs (Issue #7575)
  • The IPP and document tests now support printers that do not support US letter or ISO A4 sizes (Issue #7878)
  • The `ipptool` program can now generate PWG Raster documents dynamically for printers (Issue #7979)
  • The `ippevesubmit` program now uses the modification date of the plist files instead of the current date when generating the JSON submission file (Issue #8181)
  • The `ippfind` program did not correctly escape command-line arguments passed during the DNS-SD tests (Issue #8383)
  • The `ippevesubmit` program did not look for supported media sizes in the right place (Issue #8484)
  • Added the test numbers to all print job tests (Issue #8585)
  • Changed the I-20 prompt to insert media (Issue #8888)
  • Added 300 second timeout for all IPP and document tests (Issue #9191, Issue #9292)
  • Fixed handling of long dimension values of 0 for roll media (Issue #9393, Issue #9494)
  • Fixed the conditional requirements for “printer-supply-xxx” attributes with printers that do not have supplies.
  • Fixed some problems with the Windows DNS-SD test script.
  • Fixed the expected test counts in ippevesubmit and removed support for submitting IPP Everywhere v1.0 results.
  • Fixed the “media-col-database” and “media-col-ready” tests to allow rangeOfInteger values for the “x-dimension” and “y-dimension” member attributes which are needed for roll feed and custom media support.
  • Fixed another issue with reporting finishing options from `ippevesubmit`.
  • Fixed the media size name regular expressions to allow “.” in the name portion.

Please use the updated tools for all new submissions.

Enjoy!
