Binary data garbled

Hi All:
We are having a problem with an application that runs under
tomcat. One thing this application does is send binary files to a
remote printer. We know that the code in this application has at
least one problem. It handles the binary data as a String object and
we are told that we should not be doing this.
We'll fix this, but we hope this fixes our problem, because the
application seems to work fine for a few days. Then it gets 'stuck'
and sends garbled binary files to remote printer from that point on.
Sometimes restarting the tomcat application seems to fix things.
Sometimes rebooting the host seems to fix things. Last time nothing
did and we had to switch over to another tomcat server.
We are running the application on tomcat 6.0.14, using
jdk1.5.0.12.

Anyone have any ideas?

thanks,

George
