PRN_R_PRINTER_ACCESS_DENIED happens when the easyPDF SDK does not have permission to access the printer
Check the printer security ("Control Panel" -> "Printer", right click on a printer and go to "Properties", and then go to the "Security" tab).
Also, if you are using Windows 2003 server, try adding the following users to the list of security:
- ASP.NET Machine Account (if they use ASP.NET)
- Internet Guest Account (IUSER_)
- NETWORK SERVICE (for Windows 2003 Server only)
