I'd say because pdf files are converted to raw bits to print, ie they are
not using smarts in the printer but are converting them in the computer.
The whole original idea of Portable Document Format was to stop people
tinkering with them and making incorrect versions. If it could be split that
might defeat the object Depending on the level of protection though some
allow conversion to word or txt format and then you can do as you like but
its been my experience that if they are not tagged for reading order changes
then you get a complete mess out of the end. Also a lot of online pdf files
seem to be mere copies of a bitmap of a scanned in document and these are
just basically pictures so trying to convert then normally makes them blank.

I think you'll find that the original intention of the PDF was that it
could be read on any OS, and was platform-independent. Adobe allowed -
or perhaps I should say included - editing facilities very early on if
you were willing to pay for it. The Adobe Reader was free; Adobe Acrobat
(a suite of programs) was, if I remember correctly, on the expensive side.
Using YAPP (Yet Another PDF Printer will, ime, degrade the file and
increase its size - just chop it up:
needs some exploring but will do everything.
Thanks. Bizarrely, when I downloaded the 'source' file again the pdf
print version was changed to make it the same as the new source file.
This almost led me to email the pages that needed to be taken out.
I think I will be following your advice in future!
