Routing Structure

The spooler includes a flexible routing structure whose function is to direct jobs to print

devices. The routing structure consists of a set of locations, logically organized into

groups, and connections between locations and print devices.

Locations

A location is the logical destination of a job (as opposed to the physical destination,

which is a print device). At the time each job enters the spooler subsystem, it is

associated with a location. If a device is associated with that location, then the job

prints on that device.

Location names have two parts: a group name and a destination name. The group

name is always preceded by the # symbol. For example, #RED.LP is a valid

location name.

Table 1-6 lists the default attributes of locations and the Spoolcom LOC subcommands

used to change them.

For a job to print on a device, the job location must be connected to that device.

Connecting Devices and Locations

The Spoolcom LOC DEV command establishes connections between devices and

locations. You can connect a specific location to a device or all locations with a

specific destination name to a device.

To connect a specific location to a device, you make a single connection. You make

additional connections to that device with subsequent LOC DEV commands. To

connect all locations with a specific destination name to a device, you make several

connections at the same time. However, the LOC DEV command applies only to

existing locations. For example, if the existing routing structure includes two locations,

#RED.LP and #BLUE.LP, the command LOC LP, DEV $LP would associate the device

$LP to both locations. If you create a third location, #GREEN.LP, use another LOC

DEV command to connect $LP.

It is not possible to connect more than one device to the same location. However, it is

possible to connect multiple devices to a single group. In this case, the group will

contain at least one destination name for each device connected to it. Using Spoolcom
