For a new project, I have to create certiticates to visitors, by a form with an incremental number. These forms must create a PDF, or other file type, in which we can place the placehorlders where they have to be printed on the certificate, partially pre-printed.
And all these certificates must be printed in 1 command, from date to date.
Unfortunately, we don't have any extension like that. Our Events Booking has option to allow registrants to register, and generate certificates for these registrants. However, these registrants will have to download certificate manually themself (no option to print all certificates using one command)
