-------------------------------------
Hi Noel,
thanks for the very quick response.
Unfortunately, we can't call a different method - our PrintService is actually
based on this code:
http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Printing/PrintUtilities.java
(we renamed PrintUtilities to PrintService, we added a bit of code to better
support scaling content to the page but nothing of significance has been
modified; I've also attached the original file to this issue).
Ultimately, what we're printing is an AWT Component, so there's no Pivot
(conceptually) at this level (PrintService class is in a JAR "low" in our
dependency graph and does not depend on Pivot in any way).
There is a way for you to detect this situation - Graphics instance will be of
a different type when you print - it will be PrintGraphics. This has been
confirmed by an unrelated patch for the issue 805:
https://issues.apache.org/jira/browse/PIVOT-805
Hope this helps, if not, just let me know. We're very grateful for your support
and all the effort in building Pivot. Keep up the good work!

> Issue Type: Bug
> Components: wtk, wtk-terra
> Affects Versions: 2.0

> Reporter: Drazen Dotlic

> Printing using Java's Printable interface... We have a single Pivot Window
> (it's an applet) and the layout isn't really complicated. Implementing print
> method of the Printable interface in our case boils down to drawing into the
> provided Graphics.
> This has worked perfectly until recently (not sure which version broke
> things, but we're talking last few weeks). Now when we print we get an "Out
> of Memory" exception. Call stack does not show any obvious anomalies like
> infinite loops and such, here it is:
