Why am I unable to print in MATLAB using CUPS 1.3.4?

I am trying to print in MATLAB 7.5 (R2007b) and am getting Java errors. I am unable to print within MATLAB, but can print from other applications. I am using CUPS version 1.3.4 and have Java 1.6, but have also tried other versions of Java.

The following report discusses the CUPS issue:

https://bugs.java.com/bugdatabase/

referencing problems with /usr/lib/libcups.so

This is a soft link that is not usually created, but (at least in Debian) comes with the libcupsys2-dev package (which in turn is installed by other packages, i.e. when one wants to configure the kernel with a GUI menu).

Attempting to delete this soft link may cause MATLAB to be able to print again.
