Hi,

I found the reason for my jam.  It was because I was asking printer plugin to 
print output to such a big scale that thousands of sheets would have needed for 
covering the whole area.  While the original scale 1:12 000 000 I were asking 
for 1:5000. Well, that's the scale we are always printing to so I did not think 
too much when selecting the scale. It appeared to be so that an incautious user 
can entice the plugin to try something it cannot handle.  Perhaps the plugin 
could do a fast feasibility test here, asking something like 'Do you really 
want to print 22000 sheets?'.

I could also finally kill OpenJUMP after a very long wait.  Java process was 
just taking +99% of processor time and task manager was reacting very, very 
slowly. We have faced similar situation with Java taking almost all processor 
time and virtually blocking the whole system with our own Java applications 
when they face some unexpected problem.

Otherwise the printer plugin looks good, also with WMS imagery.  We need an 
accurate 1:5000 scale on paper, do you think your plugin can handle it? With 
our existing application we had to work hard before we managed to make it print 
to accurate scale with any printer/driver combination.
