Runs on Windows XP, Vista, 7 / 8 and Windows Server 2003, 2008, 2012, both in 32 and 64-bit systems. It may run on other operating systems inside a Virtual Machine, but we do not offer technical support for running HTMLPrint outside Windows.
Calling HTMLPrint from a System Service. By default Windows services log using the SYSTEM, which is restricted and doesn't have rights to resources like a networked printer, therefore when calling HTMLPrint from a service, since it inherits the service privileges, it will not be able to connect to any printer unless the service has access to the system printers.
HTMLPrint is not designed to be called from a D.O.S. or DirectX application.
.NET is not required to run HTMLPrint.
HTMLPrint is a stand alone application that does not require having installed any Internet Browser. It doesn't use Internet Explorer and hence is not affected for Windows updates.
