Interesting.... how might I go about testing this? Could I change the
renderer and how would I do it? Could I test this by re-arranging PCL code
in the document I produce?
I render an XML stream into a PCL document, then I send it to the printer in
a separate step. How could I 'band' this?

Hi
I don't know much about PCL, but I know this: PCL laser printers usually
build a whole page in memory and then print it to paper. They normally
have a decent amount of memory. Especially older ink jet printers like
yours only have a small buffer, so the page has to be delivered in bands
(I think). That's probably what causes your problems. Maybe the PCL
renderer would have to be changed so it can output a page as a sequence
of bands. To visualize, see here:
+---------+
| Band 1 |
+---------+
| Band 2 |
+---------+
| Band 4 |
+---------+
| etc. |
+---------+

+---------+
I think this is really what messes up your headers and footers.
