Hosted Environment Printing
Printing from the Touchworks EHR requires connectivity between the EEHR Print Server (Message Server) and the individual printers. In a LAN or WAN setting, this is easily accomplished because the printers are typically on the same network as the Print server. In a hosted (MSO or ASP) model, where the individual practices are geographically dispersed and mostly connected through the public Internet, a VPN device must be used to allow the centralized Print Server to communicate with the local printers at the individual locations.
As a result, local PC printer configurations are irrelevant to the local Touchworks EHR application and all printers are loaded directly onto the [[TouchWorks Print Server]|EEHR Print Server]. Each individual practice that will be using the system will require a site-to-site VPN. This tunnel will allow each of their local printers to be added to the centralized EEHR Print server (Message Server) in the datacenter and can be created using a variety of VPN appliances designed for small businesses. The Cisco ASA 5505 is one model that has been successfully used to provide connectivity to private practices.
