Hi Thanks for your reply
I have used the verypdf & e-pdf and looked in to lot more but appropiate.
Requirement is:-
1) Should be callable form
java 2) Bulk conversion and printing (as in case of batch)
3) Multithread support as in case of web application
I do understand the they use something very specific because they install something like printer driver but i am not sure are they converting the excel --> image --> pdf or excel --> pdf.
