In an effort to avoid spending 10 minutes watching the disc light while
I simply try to print a large raster, I tried experimenting with banding
the output, since what passes for documentation in the MS world
implies that the system doesn't try so annoyingly hard to be `helpful'
in that situation:-).

However, code which previsouly worked now doesn't, in particular, when
I call the NEXTBAND printer escape, I get a
`Null Selector (Read)'
fault, with
'Invalid handle passed to KERNEL GLOBALHANDLE+000c'
reported as the last error.

The question is, which handle, and why?  The printer device context is
unchanged from the previous, non-banding code, which worked perfectly.
There don't appear to be any other handles either used by me or required
from me...  so does anyone know what causes this?

[All this running 3.1 in enhanced mode, if that makes a difference
to your reply...]
