No, however you might report this bug to the Apple folks - the
apps should be defaulting to the width and height specified in
the imageable area, not what they think is the correct orientation.

Aside from that, you may just need to include code in your filter to
read the entire page into memory (fortunately your pages aren't that
large) and then step horizontally or vertically as you process each
line.

With CUPS 1.2, you'll also have access to the cupsImage functions
which allow you to manage large images and read rows or columns as
needed.
