I have not had this problem on Kubuntu 10.10. However, FF will often only
print the first page of a long html document and truncate it. The fact that
it is happening with browsers and not other programmes may have something to
do with encoding and how the application deals with it. That is only a guess
as I have seen nothing like this myself. I might try another browser and see
if it repeats itself with that, say Chromium or Rekonq (which is part of
Kubuntu, but uses webkit and not khtml as Konqueror does). FF uses gecko. If
all three engines produce the same error then I would think that it is
something else.
