Install network printer via web application (html)

Question

I'm trying to write a simple web interface to allow users to install one of a few predefined network printers. I had initally thought this would be a simple task, as I can easily install printers via the run command by hitting the printer dead on (\printserv\printername). I had planned to either use that in the tag, or prefix it with a "file://" but both methods result in the following error

"\printserv\printername is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions."

I know I have permission to use this resource as I can install it via the run command. Any idea what I may be doing wrong, or an alternative solution?
