Here you are Bruno - its in the paragraph after the one you quoted
form my posting.

In that case poppler leaves a blank space equivalent as far as I can
tell equal in size to the image that Acroibat Reader would normally
insert, but does not provide any of the attendant functionality that
would normally accompany various \pdfcomments.

As far as I know only Acrobat Reader renders most of the standard,
everything else renders less.

No I think Stefan has postscript being sent directly to printers in
the Windows versions of the Tw devlopment runs, which then defaults to
a bitmap of the currently visible area of the previewer if PostScripot
is not useful to the printer - is that right Steffan?
