Bug Description
Printers conforming to the new IPP Everywhere standard (of the Printing Working Group, PWG, http://
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/
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 "CreateIPPPrint
[Testcase]
Set "CreateIPPPrint
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.

by the PPD file (LP: #1637583).
