Contol file type "PDF"

My script print incoming pdf´s and move them to the folder “printed”.
But I like to control the file type and not only the filename (.pdf) so that are only pdf-files printed.

How can i do that?

Please help me!
Many thanks…

you can do

if file type of (info for  this_item) is "PDF " -- with 1 space
then   ----
end if

you dont need a tell Finder block for this
