I used it in a major project long time ago
Here is what I do remember
You should go to activepdf site, there is a procedure to follow and get it to work
Also there are some limitations - you should be carfull of.
you have to intall it as a plugins
<cfoutput>
<EMBED TYPE="application/x-pdfprint"
DOMAIN="#PDFPRINT_DOMAIN#" -- You have to have these info
license="#PRINTER_LICENSE#" -- You have to have these info
baseurl= "Base Url which has your PDFs"
changedefaultprinter=true
silent=true
pdfurl="all PDFs names " savefile=false timeout="30"
redirect="Return to a page"
>
</cfoutput>
Good luck
