Hi,
I'll be attending the OpenPrinting Summit [1] to discuss how to complete
the Common Printing Dialog [2] and integrate it into KDE and Qt. I'm
looking for any feedback people may have about the CPD, and any
questions you want me to ask while I'm there.
Many thanks, John, for never giving up with improved printing in KDE!
There a two main issues I see with the current approach of the CPD, and if
possible, you could bring them up in the discussion.
First, regarding the "common" part of the printing dialog, I hope that using a
common denominator of features offered in all operating systems does not
reduce the feature set again; we already went through it. (I guess you know
the existing bug reports. It boils down to the major feature loss that we got
when killing KDE 3.x printing system.)
The new printing dialog should not be shy on options, such as pamphlet
printing, customizable filters, and (most importantly) application specific
options with the ability to allow saving settings in global or application
specific profiles.
The second concern is about the D-Bus API. I hope that it will still be
possible to get a fast in-application preview with it when using the native
API.
For example, I love how the current Qt printing preview dialog just copies
image pointers in the QtPrinter painting engine, so that the preview renders
literally the same images as the application has in memory, without copying
the actual data. The Qt printing preview is also very fast in scrolling and
zooming, I doubt it would be possible with a program that effectively "just"
tries to parse PostScript or PDF printer files just to generate the preview.
Also on the agenda is integrated end-to-end Colour Management possibly
using colord [4], something I know absolutly nothing about, so any
feedback or suggestions people have on that will be very welcome. For
starters the dependencies for colord are glib and policykit.
Kai-Uwe Behrmann (maintainer of KDE color management applications) can
help you here. Grab him on http://www.oyranos.org/ and make sure he attends
the meeting ;)
It would be really cool to have joined you to talk about colour
management with KDE. However I am very likely to be swamped with work
during this time.
With the help of OpenICC[1] some work has been done inside the Oyranos
project about printing. The Kolor Manager configuration panel[2] shows
some of these. It would be cool for CPD to deploy Oyranos device ICC
profile configuration to create a good user experience. I am about
preparing some schematic diagrams, which can give some condensed input
from the latest OpenICC discussions around linux colour managed printing.
kind regards
Kai-Uwe Behrmann
