Public bug reported:
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.
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.
