Now I only get DMA write timeout
For more or less very empty pages the come out very fast, for full
pages there is a delay of about 3-4 seconds from one page to the next.
Is this because the printer needs the time or because some empty buufers?

To say it in other words. Is the timeout between pages existent
because the printer needs as long to build up the page or is
it dependen on the low-level-driver of linux (or, in connection wit
the first possibility, with a `bad' or `slow' implementation of
the ghostscript driver output)?

I will look for it ;-)
