cups-filters (1.11.4-0ubuntu2.1) yakkety-proposed; urgency=medium

  * cups-browsed, gstoraster, pdftoraster: Assorted fixes to make IPP
Everywhere printers correctly working (LP: #1637583):
- MIME conversion rules for PWG Raster output using gstoraster and
  pdftoraster.
- Let gstoraster and pdftoraster output PWG Raster instead of CUPS
  Raster for IPP Everywhere printers.
- Let pdftoraster generate correct PWG Raster (full page bitmaps
  without removal of unprintable borders).
- Let pdftopdf log the pages of PWG Raster jobs in page_log.
- Let cups-browsed also auto-create queues only for IPP Everywhere
  printers and not for legacy IPP printers.

[Bug 1637583] Re: PWG Raster printing on IPP Everywhere printers not working correctly

[Till Kamppeter]

Installed and tested the cups-filters and ghostscript packages from
yakkety-proposed. Printed several jobs on different (emulated) IPP
Everywhere printers (PWG-Raster-only, PDF, color, bw, ...). All print
without using mutool (using Ghostscript instead). Outcoming files are
correct (borderless PWG Raster or PDF). cups-browsed auto-creates the
appropriate print queues when an IPP Everywhere printer is present in
the local network.

Everything working as intended. SRU verified.

[Bug 1637583] Re: PWG Raster printing on IPP Everywhere printers not working correctly

[Till Kamppeter]

** Description changed:

  Printers conforming to the new IPP Everywhere standard (of the Printing
- Working Group, PWG, are starting to come onto the market. These printers
- are capable to inform the clients computers about all their capabilities
- (paper sizes, resolutions, finishers, ...) via IPP and understand known
- standard page description languages (always PWG Raster, but can also
- understand PostScript, PDF, JPEG, and/or PCL). So no drivers for these
- printers are needed. With CUPS, cups-filters, and one of Ghostscript,
- Poppler, or MuPDF they are fully supported.
+ Working Group, PWG, http://www.pwg.org/) are starting to come onto the
+ market. These printers are capable to inform the clients computers about
+ all their capabilities (paper sizes, resolutions, finishers, ...) via
+ IPP and understand known standard page description languages (always PWG
+ Raster, but can also understand PostScript, PDF, JPEG, and/or PCL). So
+ no drivers for these printers are needed. With CUPS, cups-filters, and
+ one of Ghostscript, Poppler, or MuPDF they are fully supported.
  
  Yakkety is intended to support them, but getting my hands on an IPP
  Everywhere printer (which takes PWG Raster as inpout format) I have
  found some issues:
  
  - CUPS selects a filter chain using MuPDF but MuPDF is not installed by
  default.
  
  - In contrary to CUPS Raster, PWG Raster contains a full page bitmap of
  the page, including the unprintable margins. Margins in the header are
  set to zero.
  
  - Filter chains could send CUPS Raster instead of PWG Raster.
  
  - Printed pages are not logged in /var/log/cups/page_log.
  
  All these issued are fixed in cups-filters 1.11.5 and in a patch to
  Ghostscript (already upstream).
  
  This bug report is for an SRU for Yakkety to fix the issues also there.
+ 
+ [Impact]
+ 
+ With "CreateIPPPrinterQueues Yes" set in /etc/cups/cups-browsed.conf IPP
+ Everywhere printers are discovered in the network and automatically set
+ up but they only print if mutool (package mupdf-tools) is installed.
+ This leaves users with non-working print queues.
+ 
+ [Testcase]
+ 
+ Set "CreateIPPPrinterQueues Yes" in /etc/cups/cups-browsed.conf and
+ restart cups-browsed. If an IPP Everywhere printer is in the network, it
+ will be detected but you cannot print on the auto-generated queue. After
+ installing the mupdf-tools package printing works.
+ 
+ With the fixed cups-filters and Ghostscript installed mupdf-tools is not
+ needed. Jobs get filtered via Ghostscript and printing on the IPP
+ Everywhere printer works.
+ 
+ [Regression Potential]
+ 
+ Small, as changes in the filter chain only happen if PWG Raster is
+ involved and this happens only with IPP Everywhere printers. Only the
+ output of PWG Raster and not of any other format is modified.
