Actually, that was a lousy answer from me, via DTS. I have a better
answer now though. From the Jaguar NSPrintInfo release notes at
<http://developer.apple.com/techpubs/macosx/ReleaseNotes/AppKit.html>:
"It is important in many applications to be able to reliably determine
the maximum imageable area of a printed page. A new method has been
added to NSPrintInfo:
- (NSRect)imageablePageBounds;
Returns the imageable area of a sheet of paper specified by this
object, taking into account the current printer, paper size, and
orientation settings, but not scaling. "Imageable area" is the maximum
area that can possibly be marked on by the printer hardware, not the
area defined by the current margin settings. The rectangle is in a
coordinate space measured by points, with (0, 0) being the lower-left
corner of the oriented sheet and (paperWidth, paperHeight) being the
upper-right corner of the oriented sheet. The imageable bounds may
extend past the edges of the sheet when, for example, a printer driver
specifies it so that borderless printing can be done reliably."
I saw this API and didn't find it very useful. I need to think again
about it but my first thought was that to get the margin values, I
would have to compute them from the pageSize values and the NSRect
returned by this method. Knowing that I would have to add code to check
for the existence of this method on 10.1.
A good printing example could be a good addition to the Cocoa Sample
code section as TextEdit and Sketch are not working correctly (same
issue with the 1 inch margin) in 10.2.
