Surely the point of a password is to stop people opening it ( or printing it )
without the password?
I wouldn’t be massively impressed if you took one of my documents I has
disallowed printing and then did just that.
And isn’t that error message nothing to do with iText?

Subject: [iText-questions] Use of password protected PDFs
Hello.
I've experiencing some problem using protected PDFs.
I've been asked to make a small java program that shows a list of PDFs, allows
the user to see them in a viewer and to print them with the application of a
watermark on the printed copy.
First of all I looked if it was possible to launch the PDFs in acrobat reader
disabling the printing command, but after some search over the internet it
didn't looked possible, so I developed a small viewer using the PDFrenderer
library.
The printing part, I used iText to process the PDF applying a watermark page by
page, save it in a temporary file and then print the temporary file.
With PDFs I printed the program works fine, both the viewer and the printer
work properly, but using PDFs protected, in both the modules I get the same
error:
com.sun.pdfview.PDFParseException: Unknown command: qq
at com.sun.pdfview.PDFParser.iterate(PDFParser.java:800)
at com.sun.pdfview.BaseWatchable.run(BaseWatchable.java:101)
at java.lang.Thread.run(Thread.java:662)
when I call the method getPage(int pageNum) of the class PDFFile.
I found on the internet that the problem seem quite common, but couldn't
understand how to get rid of it. Someone can help?
Thanx in advance
