Final question for today:
OK, I created a NSView subclass. The class implements the printing
code for countingpages
and the printing dialog generates pages. ok.
The problem: All pages are blank.
My custom NSView is allocated in code and I can't pass a drawing
context - since the
printing system should papare one for me.
I searched Apple's docs and several other sites and tutorials. All
explain printing -
using built-in views. Some subclass views - but don't print them.
Any hints? Some dummy 'hello worl' drawing NSView which really prints
available?

Unless you want to exactly print what's on screen, the best
approach is to construct your own "print view" as you suspected. I
wouldn't bother creating it in IB, just create it programatically.
The best approach depends entirely on what you're trying to
print. If you're only trying to print something in a table, you can
of course print the table directly, but you get all the widgets
(like shiny column headers, any controls you have, etc).
To do it "right" (ie, you want options, formats, etc.) you should
create a custom view that lays the data out properly (or according
to user options, whatever you like), then print it.
To *really* get complicated, you can use PDFKit and create a
fully-formated document. This may be preferable if you're going to
be generating anything exceedingly "pretty" (such as a well-
formatted report-style printout). You could alternatively use a web
view from WebKit along with some on-the-fly HTML and a style sheet.
It might be easier for you.
Again, it entirely depends on what you're trying to accomplish.
Start out small, learn the basics, then expand. :-)

OK, then let me rephrase: Should I create a new window in IB, drop a
special printer formatted table to the window and assign this to the
print operation?
Or should I create a NSView somehow programmatically and subclass its
draw method?
I inspected your link already and the code works fine. But now, I
need to
link this to the content in certain parts of my current document/
window.
Sorry to be not very precise. I do search the correct entry point...

This really has nothing at all to do with Core Data. As long as
you know how to retrieve the data you want to print, all the
standard printing tutorials still apply.
I recommend giving the following a good read, if you haven't
already:

Printing/index.html#//apple_ref/doc/uid/10000083i

After a while, I'm back on the cocoa list - and started to love
Core Data.
My first little app based on Core Data work fine, but doesn't
print.
I managed to prepare a printer context and print a screen view,
actually
a NSTableView. Naturally, this doesn't look very nice.
Thus I'd like to find a tutorial, which explains how to map my
ArrayController's data
to a 'printer-targeted' view and print it.
Do we have any special Core Data related printing features? E.g.
I could imagine a
'print-window' which then gets sized to the printer some way.
Any pointer regarding the best practice approach?
