Re: Printing on MacOSX (Rowan Christmas)

>What are the issues with printing support in the java runtime on OSX...

I have had printing issues for over a year. I have provided examples
(Problem ID: 3426772 on Apple Bug Reporting - reported last September) of
printing problems that we have experienced. The only response I have been
able to get from Apple is that my particular problem won't be fixed for the
release of Panther. This was a pretty big problem, since when you usually
print, you would like to have your margins set correctly. The problem I was
having was that we could not set the margins and have them print correctly
on the Apple platform (Jaguar or Panther). We have since released our Java
application, but the Apple platform still can not print correctly.

Here is a copy of the defect that I submitted to Apple (with an example
piece of source code). If you have any ideas on how to get the margins to
work, please send me any ideas...

Problem ID: 3426772 9/18/2003

* NOTES
I am using a JEditorPane as the object I am printing from.
I am including sample code with this defect to demonstrate the problem.
Line 113 in the sample code reads:
fp.formatPageFormat(fp.setMargins("0.6","0.5","2.18","1.0"));
You can set the left,right,top, bottom margins (in inches) on this line.
The 2.18 top margin setting is what is failing on the print out. It seems
if you stick to around 1 inch margins, things will work better, but our
company letterhead doesn't like a 1" margin.

We did set up a print preview object to preview the printout, and the
preview works fine and has not been added to this example.

When running the testSwing Application, enter enough text into the
JEditfield pane to cover several pages and then hit the print button below
the pane to print the text. We are using an HP LaserJet 4050 printer.
