Pull-Print across multiple locations - Single Server

If print traffic is minimal or network bandwidth between locations sufficient to carry spooled print jobs  from the users workstation to the server and then back to the printer then this could be an extremely cost efficient method of providing pull-print functionality to an organisation with multiple office locations. This setup requires no server licenses; only device related license components.

Pros: low cost, easy to install and administer

Cons: heavy use of network bandwidth, longer delays in retrieving pull-print jobs

Pull-Print across multiple locations - Multiple, unconnected Servers

If network bandwidth does not allow the carrying of spooled jobs between office location each office can be given it's own SafeCom server. Users submit jobs to a local server and pull-print devices retrieve jobs again from a local server. No server licenses are required; only device related license components.

Pros: Low cost, easier to install and administer than a multi-server setup

Cons: Users can retrieve pull-print jobs only in the office they were submitted in. If job tracking and accounting is used data will have to be collected from each server separately.

Pull-Print in a Multi-Server setup

In a Multi-Server solution a Master Server controls the replication of user accounts across all Slave Servers. The Master also deals with failover scenarios, moving users to a new Home Server when their current server fails. Tracking and Billing information is also collected by the Master Server, either in real-time or at scheduled intervals. In a Pay solution users account data is stored with the Master. Whether Pay users can continue to print or copy when the Master becomes unavailable is configurable.  Requires a SafeCom Enterprise and one or more Additional Server licenses.

Pros: Print-roaming; Central collection of tracking data; Failover of users and pull-print devices (HP models only at present!)

Cons: Higher license costs; more complex install

High-Availability thorough Microsoft Clustering

SafeCom servers can be installed in Microsoft Cluster nodes to provide a high-availability solution. This requires a Microsoft Cluster server installation with at least two nodes as well as a SafeCom Cluster license.

Pros: High availability

Cons: High cost of clustering hardware
