Print a page WB21 ( invoice)

Hi

Does anybody know how to print a webdev page.

Iam testing options. I would ,like to be able to print an invoice to pdf. Ok normaly use the reports for that. But I need the user be able to move / reposition blocks in the invoice. They have to be able to do some customisation

Iam working on a webversion of my windows app. In that app users can use reports and queries to make a template of an invoice.
That is notpossible in webdev so have any of you done sutch a thing and if so what did you do, maybe tell in short how it is done would be greatly appreciated

regards
Allard
