Fixed in my latest unofficial update (2.3.3), David:
ftp://ftp.2rosenthals.com/ftp/pub/WordPress/plugins/wp-post-to-pdf.2.3.3.zip
I have added an option which left unchecked (the new default) will only include the header (logo, blog name, description) on the first page. When checked, the header is shown on all pages, as in previous versions.
It's up to Neerav as to whether he wants to make my patches official, but you may certainly give this build a try.
Cheers
