System Reliability

To ensure uninterrupted service, your state-of-the-art Mobile Printing Service support an infrastructure
that incorporates critical redundancy factors, thus facilitating reliable, timely, accurate and secure file
processing, transfer, and output.
•
Dual-Network Operation Centers – While we refer to the "PrinterOn Server," for simplicity, in
actuality there are clusters of server farms for load balancing. Should one center be removed from
operation, the other is always available for undisrupted service.
•
Three Inbound Internet Connections – These physically-distinct connections are managed by
two separate Internet Service Providers (ISPs). This prevents downtime caused by the loss of any
single connection or one of the ISPs.
•
Battery Backup System – In the event of a power outage, each physical location incorporates
Battery Backup Systems to prevent the loss of print job data. Furthermore, the Battery Backup
Systems are supported by generators for longer-term outages, if battery backup is not sufficient.

Data Security

Your HotSpot Printer utilizes three forms of communication with the PrinterOn Server:
1. HTTP (HyperText Transfer Protocol) – HTTP communication takes place with the Server during
the license validation process, when you register your HotSpot Printer on line.
2. HTTPS (HyperText Transfer Protocol/Secure) – HTTPS communication occurs when a print job
is submitted through the PrinterOn Web Page. 128-bit SSL encryption technology secures all
information exchange between your Web browser and the Server.
Note: Using both HTTP and HTTPS requires that data be allowed to pass through the firewall
using TCP ports 80 and 443. As most environments allow for secure Internet communications on
client computers, the HotSpot Printer does not require any special firewall configuration. If a
proxy server is used, the HotSpot Printer must be configured with a proxy user account.
Reference:
See IV. Advanced Administration, About Service Status (Screen 2), HTTP Proxy
Settings.
3. TLS (Transport Layer Security) - When emailing messages/attachments, the PrinterOn Server
will accept requests for TLS authentication. The TLS protocol is designed for secure data and file
exchange over the Internet; the client/server prevents eavesdropping, tampering, or message
forgery.
Important: After the PrinterOn Server confirms successful file transfer, all records of the
print job on the Server are deleted.
