Conﬁguring Logical Printers with DCE Security

Using Logical Printers and DCE to Restrict

Capabilities

This section describes how to use DCE to restrict access to physical

printers in combination with logical printers that restrict the use of

physical printer capabilities.

The example conﬁguration in this section has one logical printer that

does not restrict the use of physical printer capabilities but does require

DCE authorization in order for users to submit jobs to it. The other

logical printers do not require DCE authorization, but restrict the use of

certain physical printer capabilities. Alternatively, you could use DCE to

restrict who can submit jobs to all of the logical printers in the

conﬁguration.

This example conﬁguration uses the hourglass conﬁguration model, as

described in Chapter 3. An hourglass conﬁguration model has a

many-to-many relationship between logical printers and physical

printers as shown in Figure 6-11, “Using Logical Printers and DCE to

Restrict Capabilities,”. An hourglass conﬁguration has the advantage of

the printer pool conﬁguration model in that it lets you balance the

workload of jobs in your system.

The concepts illustrated by this example also apply to the funnel

conﬁguration model, which has a many-to-one relationship between

logical printers and a physical printer.

In the conﬁguration shown in Figure 6-11, “Using Logical Printers and

DCE to Restrict Capabilities,”, logical printers LogPrt15, LogPrt17, and

LogPrt18 restrict access to the capabilities of the physical printers

associated with Queue7, but do not require DCE authorization to print to

them. Logical printer LogPrt16 does not impose restrictions to

capabilities, but does require DCE authorization. Users must be

members of a DCE user group to print to this logical printer.

This conﬁguration has two physical printers receiving jobs from the

same queue. The two printers both support some of the same document

formats. This example also illustrates restricting the size of jobs at the

logical printer level. Typically, you will implement this type of restriction

at the physical printer level.
