The Document Routing Engine (DRE) is the print server. Its primary function is to enable document flow from user workstations to output devices such as printers, plotters, or MFPs and capture the document characteristics of all output. Each time a user releases a print job, DRE communicates the job characteristics to CAS.
The Equitrac Port Monitor is installed with each DRE. The Port Monitor integrates with the Windows printing subsystem and functions as part of the spooler service, allowing the Port Monitor to receive and route print jobs to parallel network-connected printers.
If there are many printers within your deployment that generate frequent throughput, you may need to deploy multiple DREs. You can designate specific printers to each DRE, balancing the overall load to streamline the data flow.
The diagram below shows a typical DRE workflow. First, a user generates a print request. The DRE Port Monitor intercepts the request before it gets to the printer and "holds" the print job while it waits for a response from CAS. CAS then checks its database and either validates the user, or denies the request. The response is sent back to DRE, and the print job is forwarded to the printer if the user was validated. If denied, the user receives a notification message on their desktop (if configured). After the job has printed, the page count and job attributes are forwarded to the CAS database for printing.
For installations that require secure document printing, you can configure DRE to hold documents in a print queue until the user releases them from an embedded device. See Enabling Secure Printing. See the Related Content for additional information.
Although DRE is a core component, it is not required in all deployments. DRE manages communications with physical printing devices. If you are only tracking copy transaction on devices with embedded devices (rather than tracking print jobs), you do not need to install the DRE component.
DRE functionality can be configured in System Manager.
