ZeroServer™ Edge Computing technology applied to printers
ZeroServer™ is an innovating technology developed by Celiveo, it uses Edge Computing and allows to remove all printing-related servers in a company to save up to 10 time the cost of printing and make printing easier, secure and robust.
The ZeroServer Architecture
No Server, No Bottleneck

ZeroServer is based on the Edge Computing distributed architecture where the intelligence is located at every node of the print architecture:
- Inside the printer or MFP whenever possible
- Inside an adapter located behind the printer otherwise
- Inside the end-users PC for ZeroServer setup
- Inside a print server if a print-server setup is requested to mix server and serverless as needed within one single architecture

Some hard facts about servers


Why Print Application Servers Are A Problem :
Application servers are not only costly, they represent a serious production risk:
- Any technical glitch on the server or software will affect all printers, all users
- Server maintenance means nobody can print or authenticate on MFPs to make a copy
- Fault tolerance requires to use even more application servers
- The more printers and sites, the more servers are required
- A central unique server is then the worst possible choice in term of risks/cost


Why Print Servers Are A Problem:
- They have a very stiff cost, in average $500 per month per server https://www.tco.microsoft.com/
- If they are failing or rebooted for maintenance purpose, no user can print
- They represent a very high security risk:
- With a simple click an IT admin can capture, view, reprint any print job from any user and can target specific users (a CFO, CEO, HR…)
- Shared print queues expose to all users eyes the print job names
- Print queues have to be managed and monitored, that can be hundreds
Why Print Servers Are Used:
- Mostly to host the printer drivers and manage access rights to print queues
- That allows to use click and print with no driver to deploy to clients
- When a new printer is installed, the new driver propagates to connected client PC
- Until Celiveo, cost tracking solution could only run on print servers




Celiveo: Scalable, Fast, Robust
No central server, no application server that orchestrates printing, no master server, no slave server.
No bottleneck, no central point of failure: same setup for 1 or 100,000 printers, that’s the direct benefit or Edge Computing.






Secure Peer to Peer Communication
Celiveo on the printer
SQL Server
- Peer to peer Secure Communication with SQL Server
- Direct writing of badge # for enrollment into SQL
- Direct badge number lookup in enrollment tables
- Direct reading of pending print jobs tickets & rules
- Direct writing of usage tracking data
- High Availability mechanism if SQL Server is down
Celiveo on the printer
Active Directory/LDAP
- Peer to peer Secure Communication with AD/LDAP
- Direct user authentication during enrollment process
- Direct writing of badge # for enrollment into AD
- Direct badge number lookup with badge # in AD
- Direct reading of user OU and groups (access control)
- High Availability mechanism if AD is not reachable
Celiveo on the MFP
End-User PC or Windows Server
- Peer to peer Secure Communication with user PC where a Celiveo client service is loaded
- Peer to peer Secure Communication with Server
- Printer/MFP requests print jobs directly from PC or Windows server
- High Availability mechanism




Celiveo ZeroServer Edge Computing Architecture provides more than the benefits found in servers
Drivers management & Distribution to client PCs
The Celiveo client software automatically downloads and applies the Windows Print driver and settings defined by the administrator for the chosen Print-Direct printer or Pull Print queue. It is even possible to deploy multiple settings/drivers for one same printer, ie with standard configuration for color, booklets, paper trays.
Cost Tracking and Reporting
Celiveo tracks print jobs using supported MFP and printers intelligence, able to report accurately partially printed documents and color documents as B&W when printed on a B&W printer. Such information is sent directly to SQL Server without going through any gateway or server and the information is buffered in case SQL is not reachable.
The Celiveo Report Center is a web application that only needs to be run when needed, it access SQL server directly to compute the tracking data and deliver reports.
