I have emailed this issue in, but here it is on the forums - just in case.
We have an application that automatically prints invoices via a web printer. When the app prints invoices for a specific department we wanted Print2Email to email an individual the invoices, but when it prints the email is never sent. I see the documents go through the Print2Email spooler, then disappear, but the email process never starts.
Print2Email will email when you are at this workstation and we test print, but when the print server prints it will not email. The print server can be directed to a standard printer and it prints fine.
Troubleshooting Steps taken:
Shared the printer
Set permissions for Everyone to access the printer.
Set permissions on the Print2Email temp folder for Everyone to have Full Control.
Gave ASP.NET and IUSR full control on both the printer and temp document folder.
