Hi Wolfgang,
I saw that you asked for some input to new features in this forum sometime last summer. I don't know if you are still interested, but if you are, you should take a look at this competing product which has a couple of features, that we're VERY interested in.

The one thing that I really miss in your product is the possiblility of adding a reciept email address as a parameter to each printjob.
I.e.: every month, we send out 800+ pages of accountstatements from Navision. We've already have a field on each clientaccount containing that client's email-address and another field (boolean) to show whether the client want to receive his accountstament via email.
The accountstatement is just the start. If I can move - let's say 50% - of all our invoiceprints to PDF as well, I could really save some forrest. We currently print around 1.000 invoices a day!
Regards,
Martin
