Bug description:
Printers conforming to the new IPP Everywhere standard (of the
Printing 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.
