Support for LCDS  D1p

Xerox Line Conditioned Data Stream (LCDS) is a Mainframe to printer, Page Description Language (PDL) that uses referenced (system-stored) commands, as well as stream-embedded (Dynamic Job Descriptor Entry) commands, to control the processing of the incoming print job. This referenced command approach to printing dramatically reduces bandwidth requirements by locating the final assembly of document elements on the printer (where resources are stored). This eliminates the need for repeatedly sending complex elements, like forms, from the host to the printer, as part of the data stream. The host only needs to send the truly variable data to the printer. The printer provides the ability to control the format of the final printed page, from outside the application generating the variable data. A simple way to visualize this type of printing is to think of preprinted forms where the printer prints variable information into blank areas of the form.

To support LCDS, the Operator or System Administrator needs to make sure that the files containing the appropriate processing commands (JDL/JDE) and supporting resources (such as forms and fonts) are installed on the system, under LCDS Resources. The System Administrator should also create and dedicate at least one specific queue on the system to process LCDS (streaming) jobs.

Note: Additional queues can be set up, through Queue Manager, each with different parameters that are pre-programmed for processing specific LCDS jobs routinely sent to the printer. Individual queues can also be set up for spooling, rather than streaming. For LCDS jobs sent over a TCP/IP connection, instead of through the Bus & Tag channel, make sure to enable VPS (VTAM Print Service) on Port 9100 and select the desired LCDS queue from the drop-down list.

Verifying the presence of the LCDS License

To print LCDS jobs and enable the LCDS Console, you must verify that the LCDS license (LCDS Interpreter) is installed and enabled on the system. To do this, follow the steps contained in the Checking Installed Options with License Manager procedure, in the Required Set Up Steps section of this guide.

Note: When you install the DocuSP software for EPS (Enterprise Printing System), along with the Groupe Set (Channel) circuit board, and Bus & Tag hardware, you should see the Online Setup tab under the Gateway selection of the Setup menu, as well as the Online Manager selection under the System menu. These are required system features for the support of LCDS (streaming) printing. The channel card is only required for sending data over bus and tag. You can still send a streaming LCDS job over TCP/IP without the channel card.

Refer to the LCDS License documentation
