Windows Server 2012 - Printing using UNC path not working

Question

Hi,
I have a problem printing using the printer's UNC path ("\\Server_Name\Printer_Hostname") to work with a web
app hosted on IIS 8. With a windows forms application the UNC path is working fine and the app prints.
With
the web app I receive an error "The data area passed to a system call is tool small". 
Also,
in the event viewer under Applications and Services Logs -> Microsoft -> PrintService -> Operational, I receive the error "The print spooler failed to reopen an existing printer connection because it could not read the configuration information
from the registry key S-1-5-82-1980832875-2702362896-1795126167-3622310632-1152289074\Printers\Connections. The print spooler could not open the registry key. This can occur if the registry key is corrupt or missing, or if the registry recently became unavailable."

I have contacted IIS forum support.
Please review the link: http://forums.iis.net/p/1213109/2079229.aspx?Re+Windows+Server+2012+Printing+using+UNC+path+not+working
Their final response:
Printing from ASP.NET using System.Drawing.Printing itself is a horrible approach, as this namespace was designed for Windows Forms only. The designers did not take everything about ASP.NET in mind, so any issue can happen. That can answer why the HP model
works while the Samsung fails, as the HP one just "happens
to work",

Similarly, System.Printing was designed just for WPF.
About which printing API to use in ASP.NET/IIS, there is no clear answer so far. Thus, your only resource is Microsoft support, who can perform further analysis (with their dedicate utilities and of course Windows source code) and might come across a solution
to help you out. This is not a trivial scenario.
